Roluos, Siem Reap, Siem Reap · 13.3360°, 103.9741°
Completed in 881 under Indravarman I as the state temple of Hariharalaya, the capital now called Roluos, Bakong is the earliest sandstone temple-mountain the Khmer built and the model for the pyramids that followed at Angkor. Its five-tiered central pyramid measures roughly 65 by 67 metres at the base and once held a linga at the summit; the present central tower is a twelfth-century replacement reflecting later religious change, and the pyramid was restored in the 1930s by the French conservator Maurice Glaize.
The plan is read as a model of the cosmos, its moats standing for the mythical oceans and its enclosing walls and terraces for the mountain ranges that ring Mount Meru.
