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.
