Buddha image in Wat Phu 

Although small and seemingly unimpressive, the side-chambers in this building may have influenced the subsequent design of Angkor Wat. The buddhas in the central chamber are modern.
The front section, of sandstone, is now occupied by four Buddha images, while the brick rear part, which formerly contained the central linga, is empty. The entire roof is missing, although a makeshift covering has been added to the front. Water from the spring which emerges from the cliff about 60 m southwest of the sanctuary was channeled along stone aqueducts into the rear chamber, continuously bathing the linga.
