Battle of Talikota
Chengalpattu dates from the early Chola dynasty of the 2nd century BCE. Chengalpattu was formerly a capital of the kings of Vijayanagara, after their defeat by the Deccan sultanates at Battle of Talikota in 1565. The fortress at Chengalpattu, built by the Vijayanagara kings in the 16th century, was of strategic importance, owing to its swampy surroundings and the lake that flanked its side.
