Chennai in one minute
Chennai — live weather, population, hidden places and cost of living, auto-updated.
Chennai began as Madraspatnam — the 1639 East India Company factory that grew Fort St George, the first English fortress in India, and the city around it. Today it is Tamil Nadu’s capital, the country’s auto-manufacturing belt, and the world capital of Carnatic music every December Margazhi season. Census 2011 counted 46.5 lakh in the corporation, 65.6 lakh in the UA — with post-expansion estimates past a crore.
The city lives outdoors — Marina Beach’s 6-km sand, Besant Nagar’s evening faces, filter-coffee tiffin rooms and Kapaleeshwarar’s gopuram in Mylapore. San Thome basilica, the Theosophical Society’s banyan and George Town’s trading lanes keep four centuries stacked along the Cooum and the coast.
