Polonnaruwa
An ancient city in the heart of the Cultural Triangle, Polonnaruwa is the second kingdom that was established on the island. Established as the capital from 1056 AD, it was the administrative centre until it fell in the 14th century, due to constant Chola invasions from India. However, many vestiges lay scattered in the present-day city, which include places of worship, monuments and relics of royalty.
