Originally a tiny layout built by Bangalore Development Authority (BDA) in the 1970s and was surrounded by villages like Gangenhalli on the west, the military campus on the east, Matadahalli by south and parts of Hebbal village by north. But close proximity to other high-profile areas like Sadashivnagar and Dollar’s colony (SanjayNagar) led to rapid development of RT Nagar. Also setting up of a Head post office on RT Nagar main road provided further impetus to the growth of RT Nagar.it is one of the posh areas in Bangalore.
Over the last few years RT Nagar has come to commonly represent many areas like MLA Layout, Gangenhalli (Ganganagar),Dinnur, SultanPalya, Kanakanagar,Manoranpalya and even Kavalabyrasandra simply because these areas fall under the RT Nagar head post office ( with Pin code 560032) jurisdiction. Even today a lot of businesses in these areas actually show “RT Nagar post” as an address line item.
