Tarnaka, is derived from ‘Tar’ which means ‘wire’ and ‘Naka’ meaning ‘guard room’. It was thus called because the Nizam barbed the area and put up a guard room to protect his fruit gardens in the area. Though the tar and naka have disappeared, the boundary still exists in the form of Osmania University Campus. Tarnaka once a fruit garden has now turned into the cradle of intellectuals pursuits with a number of research institutions like CCMB, NIN etc. Similar to Tarnaka, there are streets like Golnaka, Chatrinaka. But, the origin of these names is not known. Probably, like Tarnaka, these places must have had some guard rooms. Hayat Nagar, 16 kms away from east of Hyderabad was built by Hayath Bakshi Begum in 1626. This was the small village, where the ceremony of the first tonsure of Sultan Abdullah Qutub Shah was celebrated by his mother, Hayath Bakshi Begum, on a very grand scale of twelve days in 1631. May be because of Hayat Bakshi Begum, the place was thus known as Hayat Nagar.
