The axial temple of Wat Phu is spectacularly situated at the base of Lingaparvata. In this photo, looking east from the sanctuary partway up the mountain, we see the temple's causeway, which runs east-southeast and terminates in two grand barays (excavated reservoirs) that were probably built by Suryavarman II (1113-1150). On either side of the temple axis there are two large buildings, of unknown function, each enclosing a square courtyard.
