1. Go on a walking tour inside Fort St. George.

In search of new trading posts, the East India Company's men chose a sandy strip of land to set up shop in the early 17th century. In time, a fort was built. In time, villages around it were annexed and this came to be the core of Madras, now called Chennai. Most of the fort's built-up spaces are now occupied by the offices of the state government and Indian military forces. But much can be explored. The moat, the ramparts, St. Mary's Church, Clive House, the barracks and bungalows. The streets of the Company officials and of the traders of what was 'White Town' remain as do buildings of the 18th century. End the tour with a visit to the Fort Museum ( Open 10 am to 5 pm. Closed on Fridays. Admission fee is charged).

Tip: This is a secured campus; carry identification and avoid the areas of the local ministers' offices and the military sections. A brisk walk can take about 90mins. and is best done in the morning; best on Sunday when the campus is quiet. Entry is through the main gate.
