Polonnaruwa (Tamil - பொலநறுவை or புளத்தி நகரம் as called by Cholas) is a town. It's the main town of Polonnaruwa District in the North Central Province, Sri Lanka. Kaduruwela area is the Polonnaruwa New Town and the other part of Polonnaruwa, remains as the royal ancient city of polonnaru kingdom.
The second most ancient of Sri Lanka's kingdoms, Polonnaruwa was first declared the capital city by King Vijayabahu I, who defeated the Chola invaders in 1070 to reunite the country once more under a local leader. The Ancient City of Polonnaruwa has been declared a World Heritage Site.
One recent scientific observation is that of its climate changes: historically, Polonnaruwa had a tropical climate most of the year, although it was occasionally chilly in December and January. But in recent years the rain and chilliness has been increased noticeably. Although this is surprising to some people, it is more enjoyable for tourists. However, there is a setback, as paddy field farmers can suffer when there is too much rain.
