Phimeanakas
A large, tiered pyramid of laterite and sandstone construction, it is the tallest climbable temple in Angkor Thom, and from the top, it offers a good view of the surrounding area. The stairway on the western, or back side of the temple, affords the easiest way to climb to the top.
Unfortunately, there is an absence of carvings, and this may make it uninteresting for some, but it is still an impressive structure, and well worth exploring.
What may make it more interesting to some, is the legend associated with it. Phimeanakas was the temple of the king, and the legend says that in the golden tower that topped the temple, there dwelled a mystical serpent that would transform itself into a woman at night. In order to protect the kingdom, and to prevent a disaster befalling the kingdom, the Angkorian kings were required to make love with the serpent every night.
