This brick tower is located 3 km south of the Bakong in a secluded area. It was probably built by Jayavarman II., early 9th century.

A moat encloses the remains of five or more towers and a fire shrine. Only the central tower is still standing upright. The false doors are of sandstone, lintels and colonnettes are well executed. The entrance door at the East was sacked.

The Devata of Trapeang Phong are the first and oldest in Khmer art. They stand in niches at the wall and sit in small medallions at the upper tier. These reliefs are carved on brick and covered with stucco.

Noteworthy for its quality of its brick decoration is the base of another tower nearby.

The remains of a royal residence nearby have been recently excavated. 

Access
From Bakong you go 300 m to the West. Then you follow a raised way to the South. After 1.5 km there is a school on the right hand side. There you ask for prasat ; the footpath goes roughly to the south-east. At the end of the rainy season, the route can be under water.
