Polonnaruwa was the medieval capital of Sri Lanka from the 11th to the 13th century, and its well-preserved ruins offer one of the most ancient city experiences in Asia. The Royal Palace complex, the Gal Vihara rock temple with its carved Buddha figures, the Vatadage circular relic house and the Quadrangle of royal monuments can all be explored on foot or by bicycle along a well-marked heritage trail. Polonnaruwa is a UNESCO World Heritage Site and one of the most rewarding historical destinations in all of Sri Lanka.
