Baphuon23 temple is west of the road to the Dei Chhang Gate and near the Bayon temple. The temple was built in the 11th century, around 1060 by King Udayadityavarman II (AD 1050-1066), dedicating to Brahmanism. A hightlight of the temple is the bas-reliefs, which differ from most others as they are vignettes carved in small stone squares set one above the other on the temple walls, similar to tilling. Unfortunately few of these are visible because of the poor state of the temple.

Baphuon is a single temple-mountain sanctuary situated on the high base symbolizing Mount Meru. A rectangular sandstone wall measuring 435 by 125meters long elevated eastern approach supported by three rows of short, round columns forming a bridge to the main temple. Originally, a central tower shrine with four porches crowned the peak, but it collapsed long ago. The first, second and third levels are surrounded by concentric sandstone galleries.
