For three centuries Polonnaruwa was a royal capital of both the Chola and Sinhalese kingdoms. Although nearly 1000 years old, it’s much younger than Anuradhapura and generally in better repair (though smaller in scale).

The South Indian Chola dynasty made its capital at Polonnaruwa after conquering Anuradhapura in the late 10th century, as Polonnaruwa was a strategically better place to guard against any rebellion from the Ruhunu Sinhalese kingdom in the southeast. It also, apparently, had fewer mosquitoes! When the Sinhalese King Vijayabahu I (r 1055–1110) drove the Cholas off the island in 1070, he kept Polonnaruwa as his capital.

Under King Parakramabahu I (r 1153–86), Polonnaruwa reached its zenith. The king erected huge buildings, planned beautiful parks and, as a crowning achievement, created a 25-sq-km tank, which was so large that it was named the Parakrama Samudra (Sea of Parakrama). The present lake incorporates three older tanks, so it may not be the actual tank he created.

Parakramabahu I was followed by Nissanka Malla (r 1187–96), who virtually bankrupted the kingdom through his attempts to match his predecessors’ achievements. By the early 13th century Polonnaruwa was beginning to prove as susceptible to Indian invasion as Anuradhapura was, and eventually it, too, was abandoned and the centre of Sinhalese power shifted to the western side of the island.

In 1982, Unesco added the ancient city of Polonnaruwa to its World Heritage list.
