Though it could be believable that Asia's largest residential complex is present in India; but where in India? Patna! Patna is the capital of Bihar and certainly not amongst the most populous cities in the country. This colony was developed in 1916 when the idea of organised cities was new to India.

The Kankar Bagh Colony is spanned across 900 acres of land, near the centre of the city. This complex is well connected to the rest of the urban limits of Patna. Its name comes from the pebbles which were used in constructing pavements and cobbled paths in its initial days.
