Phimeanakas-Temple at Angkor is a Hindu temple in the Khleang style, built in the shape of a three stepped pyramid at the end of the 10th century.
The temple was the focal point of Suryavarman I's capital. The buildings there from his reign are enclosed by a wall 600 by 250 m, with five gopuram, and include the Southern and Northern Khleangs.
The tower must originally have been crowned with a golden pinnacle, as Zhou Daguan described it in his report.
The Phimeanakas pyramidal structure consists of 3 tiers of diminishing size. At the base the structure measures 35 meters long by 28 meters wide, the upper platform measures 30 meters long by 23 meters wide. A very steep stairway leads to the top on all of its four sides guarded by lion statues. Most accessible is the one on the Western side, which is equipped with a handrail. At the corners of each of the tiers are guardian elephant statues.
On top of the pyramid is a platform surrounded by small galleries. These were the first vaulted galleries to be built in Angkor, which have been copied on a grander scale in the later monuments.
