Dambulla marks the geographical centre of the island and the Cultural Triangle. It also holds its own treasure – a magnificent temple, which is a series of five caves established as a monastery in the 3rd Century BC. These caves, built at the base of a 150m high rock during the Anuradhapura (1st Century BC to 993 AD) and Polonnaruwa times (1073 to 1250), are by far the most impressive of the many cave temples found in Sri Lanka. Access is along the gentle slope of the Dambulla Rock, offering a panoramic view of the surrounding flat lands, which includes the rock fortress Sigiriya, 19kms away. Families of friendly monkeys make the climb even more interesting. Dusk brings hundreds of swooping swallows to the cave entrance.
