“Prasat Phum Pon is the oldest Khmer temple located in Sangkha district Surin (Isaan), “present-day Thailand.” ”
The complex occupies 4 ancient structures 3 brick and 1 laterite, lying in North-South direction. The big brick structure and the northern one remain in rather good condition. These two structures are among the oldest Khmer ruins in Thailand, presumably erected in the 6th - 7th centuries. The brick one in the middle and the laterite in the South were seemingly built later.
This complex was meant to be a Hindu religious site like other contemporary ones. No lingum is discovered, but in the big edifice there remains Somasutra, a pipe to convey sacred water from the platform of the statue in the central room.
