P1156 The Strand: archaeological assessment

Summary GGAT Contracts has undertaken an assessment of the archaeological effects of a proposed development, at the petrol filling station on the Strand, Swansea. The assessment reviewed information held by the regional Sites and Monuments Record and the National Monuments Record, as well as cartographic and documentary sources. Aerial photographs were examined and a site visit made. A total of thirty one sites of archaeological interest were identified through the current study, including one Listed Building (Grade II). No Scheduled Ancient Monuments, Registered Parks and Gardens or Designated Landscapes are located within the study area. Thirteen previously unrecorded sites were identified. The proposed development has been assessed as having a severe effect on two, a major effect on a further two and a minor effect on one of the known sites of archaeological interest. The effect of the development on those previously unrecorded sites has been assessed as severe in six cases, as minor in two cases and as none in the remaining five. The Urban Waterfronts Project in Southeast Wales places the development within an area of high potential for the discovery of submerged or buried maritime archaeological remains. It has been recommended that an archaeological evaluation be carried out and that is likely that a written scheme of investigation and plan for mitigation be produced based on the results of that evaluation, prior to the commencement of any development. It has also been recommended that any geo-technical works or ground investigations within the development area be monitored on site by an archaeologist.

Introduction

1.1

Planning history

1.1.1 Swansea Housing Association Ltd are preparing an application for outline planning permission for a residential redevelopment at Strand Petrol Filling Station and the surrounding area, in Swansea. The Glamorgan-Gwent Archaeological Trust, Contracts Division (GGAT Contracts) was commissioned by Swansea Housing Association Ltd to undertake a desk-based assessment in order to determine the effect of the development on the archaeological resource. 1.2

Specification and methodology for study

1.2.1 The assessment comprises a review of existing information about the archaeological resource within a 0.12 sq km study area. The study area is centred on NGR SS6586293639 and is outlined in green in figure 1. The assessment is intended to conform to the Institute of Field Archaeologists’ Standards in British Archaeology: Archaeological desk-based assessments. 1.2.2 Information recorded on the regional Sites and Monuments Record (SMR) and National Monuments Record (NMR) was assessed. Cartographic and documentary sources were studied, along with relevant published information. Current Listed Building data and information on Scheduled Ancient Monuments and registered landscapes was obtained from Cadw. Collections of aerial photographs held by the Central Register of Air Photography for Wales were examined and additional information requested from the Royal Commission on the Ancient and Historical Monuments of Wales (RCAHMW). 1.3

Assessment criteria

1.3.1 The archaeological sites within the study area are categorised in accordance with the only available criteria that are nationally agreed; these are set out in the Department of Transport/Welsh Office/Scottish Office Design Manual for Roads and Bridges paragraph 3.4 Vol. 11 Section 3 Part 2 (Cultural Heritage). Category A: national importance Category B: regional importance Category C: local importance Category D: low importance To these an additional category has been added Category U: unknown 1.3.2 The assessment of the importance of individual sites is essentially a subjective exercise based upon the experience of the project team. The importance of certain sites will be implied by their status within the statutory framework. Scheduled Ancient Monuments will always be of national importance; Listed Buildings will be of at least regional importance. Values assigned to other sites are given both in relation to their individual importance and to their context within the wider landscape. 1.3.3 The condition of individual sites and the general overall condition of surviving remains has bearing on the value of the sites themselves and on the value that they impart within a 4

P1156 The Strand: archaeological assessment

wider landscape context. The condition of sites is recorded following the system used by the GGAT SMR, using the following criteria: Intact: the site is intact Near intact: the site is nearly intact Damaged: the site has been moderately damaged Near destroyed: the site has nearly been destroyed Destroyed: the site has been destroyed Restored: the site has been restored Moved: the site has been moved (usually finds) Not known: the condition of the site is not known 1.3.4 For the purposes of desk-based assessments, rarity is assessed at regional level only. The following criteria are used: High: very few sites of this type are known Medium: the site is not unusual, but cannot be considered common Low: the site is quite common 1.3.5 Group association is where a connection between sites within the landscape can be demonstrated. These will usually be of the same period, but may include groups where the presence of an earlier site or sites has led to the formation of a later complex, or where an earlier site or sites can be shown to have acquired importance as part of a later complex. The criteria are as follows: High: the site forms part of an interconnected complex occupying a clearly definable landscape where little or no fragmentation has occurred Medium: the site is part of an interconnected complex, which is either limited in scope or badly fragmented Low: there are few or no other sites, which are associated 1.3.6 Historical association is where there is a link between the site and known historical or cultural persons or events. Prehistoric sites, which are by definition before historical evidence, cannot have any contemporary historical association, but they may acquire later associations. For the Roman and Early Medieval periods, where survival of historical evidence is poor and patchy, any contemporary documentation at all will be important. Two classifications are given for historical association, one reflecting the certainty of the identification, and the other its importance. Only sites with certain or possible association can be assessed for importance, and historical association can only increase the importance of a site; the absence of it will never decrease its importance.

1.3.7 Historical association- identification Certain Possible Unknown 5

P1156 The Strand: archaeological assessment

1.3.8 Historical association- importance High Medium Low 1.3.9 The assignment of values to identified interests requires consideration of the reliability and accuracy of the source data, ranging from fully-recorded features seen in open excavation to antiquarian comments on finds of note from a poorly-defined location. The confidence with which the values have been assigned is noted, using the following criteria: High: existing information is reliable and detailed Medium: existing information is apparently reliable but limited in detail Low: existing information is too limited to allow its reliability to be assessed 1.3.10 The effect of the proposal on the archaeological resource has been assessed using the following criteria: Severe: total loss Major: significant loss, likely to result in a reduction of value of the surviving site Minor: loss unlikely to result in a reduction of value of the surviving site None: no identifiable effect Beneficial: development will protect, preserve or enhance the site better than if the development did not occur

Background

2.1

Location, Topography and Geology

2.1.1 The study area is centred on NGR SS 65862 93639 on The Strand north of Kings Lane to the west of the River Tawe and east of the High Street. The High Street sits at approximately 16m OD on a ridge of glacial drift that has been extensively terraced and that slopes down to The Strand at 8m OD. The Strand had formed the western bank of the River Tawe’s original course, prior to the construction of the New Cut in the 1840’s when flow of the river was significantly altered to its present course. Though the river had been moving gradually east due the construction of numerous wharves, docks, coal yards and other industrial premises throughout the 18th and early 19th centuries. The original course of the river survived until the 1970’s as the remnants of North Dock Basin when it was filled as part of the Parc Tawe development, although infilling of the North Dock had begun much earlier during the 1930’s and had continued in earnest in the 1950’s when large parts of bomb damaged Swansea had been used to fill the dock. 2.1.2 Swansea is situated on Carboniferous Coal measures; the extraction of coal from this area has greatly influenced the history and development of the region. The soils over the study area are largely un-surveyed but will likely include alluvium associated with the River Tawe (SSEW 1983). 2.2

Walkover survey

2.2.1 The development area is a roughly square parcel of land situated on a disused petrol filling station; this was the Strand Petrol Filling Station. The land immediately surrounding the development area is currently in use as office buildings and a multi-storey car park and is bounded on two sides by the Strand and on the third by New Cut. A walkover survey was carried out on 27/09/06 to identify any previously unrecorded sites and to observe the condition of known sites with the study area; the sites were recorded and photographed, plates 1-6 Appendix II.

Historical & Archaeological background

2.3.1 Prehistoric (up to AD43) and Roman (AD43 to 410) Evidence for activity through the Prehistoric and Roman periods in this region is limited to a few isolated find spots within the bounds of modern Swansea, including a sherd of Roman cooking pot (PRN 00424w) from the alluvium at the edge of the North Dock and a group of Roman coins of the early 4th century found in Castle Street (PRN 00423w). These finds indicate that there was some activity in the vicinity during these periods, though as yet no settlement evidence has been found. 2.3.2 Early Medieval (410 to 1066) It is thought that Swansea originated as a Scandinavian trading port in the 9th and 10th centuries; the place name of ‘Swansea’ is believed to derive from the Scandinavian personal name ‘Sveinn’, and ‘ey’ meaning an island or inlet (Williams 1990). This place name evidence may suggest trading activity focused around the natural harbour at the mouth of the River Tawe with associated settlement being established nearby (Howell 2000). However there is a lack of any conclusive physical evidence to support this assertion. 2.3.3 Medieval (1066 to 1485) The first definite record of Swansea appears in the twelfth century in a charter granted by William Earl of Warwick when the original motte-and-bailey earth and timber castle was founded as the caput or administrative centre for the Norman lordship of Gower. This castle was rebuilt in stone probably during the thirteenth century at its largest occupying land extending from College Street/Welcome Lane in the north to Caer Street/Castle Lane at the south, and from Princess Way in the west to the Strand in the east (Evans 1983; RCAHMW 2000, 346-52). A town quickly grew up around the castle that is also recorded in the charter and like the castle was subject to frequent attacks by the Welsh in eleventh and twelfth centuries. The town is known to have eventually been defended by a wall and ditch; a number of excavations around Wind Street and the High Street have uncovered parts of this medieval town wall. Swansea flourished and grew during the earlier medieval period a suburb called Bovetown was established along High Street to the north outside of the medieval town walls (Calendar of Close Rolls 1429-35). However a series of attacks during the Glyndwr rebellion and plagues through the thirteenth and fourteenth centuries brought about a marked decline in the fortunes of Swansea; a reduced population resulted in slowed trade and production within the town. 2.3.4 Post-medieval, Industrial, and modern (1485 to present) Swansea was ideally situated to take advantage of the seventeenth century expansions in coal trade. The town was located close to a ready supply of coal and was situated on a tidal river that provided an ideal communication route for trade. Swansea became one of the busiest ports in South Wales; a contemporary source stating that Swansea carried on “a significant trade in coals, pottery and copper” (G Lord Lytleton, 1781). The establishment of metal industry and the construction of numerous smelting works along the Tawe, including the Cambrian Copper Works, located partially within the study area, founded by 10

P1156 The Strand: archaeological assessment

Quaker James Griffiths in 1720, were a product of this trade. Ceramic industry also forms part of Swansea’s industrial heritage with the establishment of the Cambrian pottery leased to William Coles in 1764 on the site of the former Cambrian Copper Works. The Cambrian pottery managed by George Hayes and Lewis Weston Dillwyn became renowned for its variety and high quality earthenware and porcelain. The pottery was taken over by its rival the adjacent Glamorgan Pottery in 1838 after a period of intense competition. Eventually this large-scale pottery industry declined due a multiplicity of factors including fierce competition from smaller local companies. During the construction of the multi-storey on the Strand an underground brick vaulted chamber was discovered, a large quantity of ceramics were found in the vault, upon examination this was identified as a drying room serving the Glamorgan Pottery (Sell pers comm.). Continuing large-scale coal and metal trade and production supported an increased population in Swansea up until a period of decline following the First World War and the Second World Wars when extensive bombing of the town centre added to the decline of the town. 2.4

The Study area

2.4.1 Documentary evidence and historic mapping with coverage of the area show changes that have taken place in the shape and location of the waterfront along the Strand at Swansea through the eighteenth, nineteenth and twentieth centuries. Documents dated to 1703 mention the lease of land located within the study area by the Corporation and the Duke of Beaufort who used the land as “coal places” or “coal banks” for the stockpiling of coal prior to its export (Morris 2005). The Strand is mentioned again in a lease dating to 1720 permitting the construction and operation of the only copper works within the borough, the Cambrian Copper Works. 2.4.2 Water power was used to supply the power needed to operate the copper works, to ensure enough water was always available a ‘large mill pond’ was created just to the north of the copper works. It is likely that a mill pond may have already existed in this location and this later ‘large mill pond’ was actually an extension to a pre-existing medieval mill pond. A mill pond can be seen on the 1843 tithe map and again on the 1852 Swansea Local Board of Health Plan (consulted but not reproduced). Swansea canal constructed in 179496 crossed though the west side of the mill pond making it almost redundant as from then on the wastewater from the canal could be harnessed to provide the water required to power the works. The mill pond appears to have been incorporated into the canal system at some stage appearing on the 1879 1st edition OS and subsequent maps as a ‘lock basin’. 2.4.3 The course of the river on the 1843 tithe (figure 3 appendix 1) is shown curving in towards a dock (identified as Pottery Dock in figure 8) now under the proposed development area. In the nine years between the 1843 tithe and 1852 board of health map the New Cut was constructed radically altering the course of the river, effectively turning its original course into the new North Dock. The inward curve and Pottery Dock visible in 1843 are no longer visible by 1852 probably being in filled during the alteration of the original riverfront that is now North Dock. By 1879 (1st edition OS, figure 4) what remains of the canal, has largely been replaced by a railway line serving the dock and the Glamorgan and Cambrian potteries are now a coal wharf and fuel works respectively. The development area still sits partially over the river, now North Dock, in the 1st to 3 rd editions of the OS map and the west side of Pottery Bridge, a swing bridge crossing the 11

P1156 The Strand: archaeological assessment

North Dock. An extension to the fuel works in the 1899 2nd edition OS map (figure 5) replaces the coal wharf seen in the 1st edition OS map, the development area then remains relatively unchanged from the second edition of the OS map through to the 1919 third edition OS map (figure 6) until the infilling of North Dock and the construction of Parc Tawe in 1970’s.

Archaeological Interests

3.1.1 There are thirty one sites of archaeological interest identified within the study area (Tables 1 & 2; figure 1). These include one listed building (Grade II); St Matthew’s Church, no Scheduled Ancient Monuments, Registered Parks and Gardens or Designated Landscapes are present. Thirteen previously unrecorded sites were identified by the current study. Further information relating to these interests can be found in the gazetteer in Appendix III. 3.1.2 Numbers with a letter suffix are Primary Record Numbers (PRNs) in the regional Sites and Monuments Record (SMR). Five and six figure numbers without a letter suffix are National Primary Record Numbers (NPRN’s) of the National Monuments Record, as supplied to the SMR under the ENDEX agreement. Numbers with a ‘LB’ prefix are Listed Buildings, as provided by Cadw. Sites represented by STR followed by a two-digit number correspond to new or potential sites identified by the current study.

Assessment

4.1 The effect of the development has been assessed based on the assumption that the works will be such that all archaeological deposits will be destroyed. 4.2

Effect on known sites (Table 3)

4.2.1 Nineteen known sites of archaeological interest were identified; of these only two are located within the outline of the proposed development area. The effect of the proposed development has been assessed as severe in both these cases: the Glamorgan Pottery and Canal Wharves (40678 and 01046.38w). No above ground remains survive for any of the known interests and the potential for encountering below ground remains is currently unknown, to allow for this potential effects of the proposed development has been assessed at a high level. 4.2.2 Outside of the proposed development area the effect of development has been assessed as either minor, in the case of Cambrian Pottery (00831w/40796), the Pottery Mill at Cambrian Pottery (04644w) and Wharves (04647w), as it is likely that at least part of these may extend into the development area. In the case of the remaining known sites of St Matthew's Church and Churchyard, Numbers 75-78 High Street, Sion Chapel, Swansea Railway Station, Swansea Engine Shed the Old Quaker Meeting House and Burial Ground, the Friends' Meeting House, the Elysium Club, New Cut Lock and Weir, Pipe Quay and the Arrowhead find spot (LB11584/00429w, 05254w, 02913w, 03485w/89580, 03827w/34874, 03828w/34872, 03256w/91405, 02357w, 03573w/90360, 02912w, 04645w, 04662w, 04648w and 00452w) the effect has been assessed as none.

4.3

Effect of development on newly identified and potential sites (Table 4)

4.3.1 Thirteen new sites have been identified within the wider study area, however only six of these lie within the development area: none of these survive above ground and the nature and extent of survival of any below ground remains is currently unknown. As a result the effect of the proposed development on these sites has been assessed as either severe or major depending on their location either fully within or on the periphery of the proposed development area. 4.3.2 The proposed development will have a potentially severe effect on the newly identified sites of the Additional Brick Drying Chambers, North Dock, Pottery Bridge, Pottery Dock, Patent Fuel Works and Unknown Maritime Remains (STR02, STR03, STR04, STR08, STR11 and STR13) all of which lie within the outline of the proposed development area. There will also be a potentially minor effect on the remainder of the newly identified sites of the Cambrian Copper Works and Coal Wharf (STR12, STR01) that lie on the edge of or just outside the proposed development area, there will be no effect on the remainder of the newly identified sites of the Medieval Mill, Mill Pond, Canal Lock Basin, Swansea Canal and the Dock Railway (STR05, STR06, STR07, STR09 and STR10).

Unknown Maritime Remains

Potential for maritime remains

4.4.1 The proposed development area lies within a unique landscape that has been highlighted in a Cadw commissioned report assessing specifically the maritime archaeological potential of Urban Waterfronts in southeast Wales. Following the discovery, in 2002, of the remains of a medieval ship that was exceptionally well preserved, the potential for further discoveries of this nature along urban waterfronts were recognised and assessed by Howell et al. 2004. The potential to encounter previously unidentified maritime remains within the development area is high. The original river course of the Tawe followed the edge of the road that today is the Strand; previous work along the Strand has revealed wooded piling, planks and moorings along the relict riverbank. Pottery Dock (STR08) located under the development area on early mapping was later in filled and the course of the river here moved significantly east any development in this area could reveal remains of ships and or other maritime remains used in the infilling of the dock. The original course of the Tawe later became the North Dock (STR03), was in filled during the 1930’s, 1950’s and1970s; any development in the area could reveal maritime remains associated with the dock depending on the nature and extent of ground works. During the construction of Parc Tawe II in the 1990’s large fragments of monumental masonry from Victorian and Edwardian buildings from the waterfront were recovered (Maylan Pers comm.).

Mitigation

5.1.1 Historic mapping and documentary sources have highlighted six potential archaeological interests within the development area that had previously been unidentified, along with a number of known archaeological interests. The level of preservation for the majority of these archaeological interests is unknown. There has been significant building activity in the area over time including more recently the construction of a multi-storey car park and the petrol station on the Strand. It is possible that these recent developments will have caused some damage to the archaeology; however, the level of any possible damage is at present unknown and should be assessed. 5.1.2 It is recommended that an archaeological evaluation be carried out to assess and record the potential of uncovering remains of any of the newly identified and known sites of archaeological interest. This evaluation should be done before any decision on the planning application is taken as the evaluation may provide information useful for identifying potential options for minimising or avoiding damage to the archaeological resource (Welsh Office Circular 60/96 section 13). 5.1.3 It is also recommended that a written scheme of investigation and plan for mitigation be produced based on the results of the evaluation in order to provide a clear outline for a programme of continuing archaeological works prior to the commencement of any development. Additional information concerning the archaeological resource could be uncovered during any geo-technical works or ground investigations as such it is recommended that any works of this nature within the development area be monitored on site by an archaeologist as part of a watching brief.

Since then the site has been used for various industries, it is likely that many structures associated with the pottery will have been severely damaged or destroyed by the intensity of later development. During the construction of the multi-storey car park on the strand an underground brick vaulted chamber was discovered, a large quantity of ceramics were found in the vault, upon examination this was believed to be a drying room serving the Glamorgan pottery (S.Sell pers comm.).

The land on which the church stands, immediately to the north of the medieval town of Swansea, was granted to the order of St john of Jerusalem between 1156 and 1184, and the original church was built by them (Williams 1990, 18-9). The dedication was changed to St Matthew in the 1880s, since a new church in the hafod had been dedicated to St John (Morgan 1990, 200). The church was twice rebuilt in the 19th century, in 1824 and 1886, the architects being respectively William Jernigan, and Bucknall and Jennings of Swansea. There is a small churchyard attached to the church that is roughly Quadrangular in shape. Part of Edith Evans, GGAT 73 early-medieval ecclesiastical sites project, 2003-04 (yr4). Type Church

The site was first leased for "carrying on a stoneware or earthenware manufactory" to William Coles in 1764. This later became the Cambrian pottery, managed by George Hayes and Lewis Weston Dillwyn, which were celebrated for its variety and high quality of earthenware and porcelain. The pottery was taken over in 1838 by its rival the Glamorgan pottery after a period of intense competition. The site continued to be used as a pottery until 1870 when it was eventually closed and it’s buildings dismantled. Type Pottery
