Girinagar ( formerly known as Writer's Colony) is a residential area in South West Bengalooru, very close to Mysore Road. This medium-sized locality is surrounded by Nayandahalli in the west, Byatarayanapura and Deepanjali Nagar in the north, Srinagar and Banashankari in the east and Hosakerehalli in the south.Girinagar is at a lower altitude ( 865 m) compared to the rest of Bengalooru, which has an average elevation of 900 m. It is very hilly, with steep roads - being on the slope of a hill with a plateau on top. To the west of Girinagar is a hill, known as Hirannayya Gudda in Kannada. Girinagar lies in the Vrishabhavathi Valley region of Bengalooru.
Girinagar is divided into 4 phases, with the 2nd phase being the largest. It also subsumes areas such as T Block, Muneshwara Block, Nagendra Block, Avalahalli, Ganapathi Nagar and Chamundi Nagar.
Girinagar is one of the older, conservative areas of Bengalooru, with a predominantly Kannada speaking population. The population is also predominantly Hindu. This area is not very cosmopolitan and tradition is the order of the day. But nowadays the youngsters here have a blend of both modern as well as traditional values.
