According to archaeological finds, the Khmer ruins were a hospital built during the reign of Jayavarman VII in the 13th century. The principal tower has a square plan with a front porch, with a rectangular building known as Ban na lai - a library – in the southeast. These two laterite buildings were surrounded in by a stone wall with a single front entrance on the east. To the northeast outside the wall, there is a pond lined with la terite . The ruins are now well conserved by the temple nearby.
