For three centuries Polonnaruwa was a royal capital of both the Chola and Sinhalese kingdoms. Today's archaeological park is a delight to explore, with hundreds of ancient structures – tombs and temples, statues and stupas – in a sprawling forested core. Although nearly 1000 years old, it’s much younger than Anuradhapura and generally in better repair. You can see the site in a day, and the highlights in half a day.
