Kings ruled the central plains of Sri Lanka from Polonnaruwa 800 years ago, when it was a thriving commercial and religious centre. The glories of that age can be found in the archaeological treasures that still give a pretty good idea of how the city looked in its heyday. You'll find the archaeological park a delight to explore, with hundreds of ancient structures – tombs and temples, statues and stupas – in a compact core. The Quadrangle alone is worth the trip.
That Polonnaruwa is close to elephant-packed national parks only adds to its popularity. And with good accommodation and plenty of bikes for hire, the town itself makes a pleasant base for a day or two, fringed by a huge, beautiful tank with a relaxed ambience.
Nearby Kaduruwela, 4km east of Polonnaruwa, has the lion's share of banks, shops and other facilities.
