On top, 142 steps up, is a temple whose foundations date from the 6th century. Rebuilt in the 11th century, it's 12m square and 18m high. The entrance faces due north, with blind doors - decorated with bas-relief naga - on the other three sides. The lower section is laterite, while the upper reaches are made of red bricks. The finest carvings have been taken to museums in Angkor Borei, Phnom Penh and Paris.

About 50m northeast of the temple, a huge 'floating boulder' sits balanced on just three points. Vietnam can be seen 8km to the southeast.
