Ku Pon Ra Kang was constructed in the 12th/13th centuries. By its architectural style it is believed to be an arokayasala (medical station/hospital) built during the reign of King Jayavaman VII (1181-1218). Ku Pon Ra Kang consists of a single tower and porch and another building in the southeast corner of a rectangular compound with a doorway facing east. The prasat is built of laterite with sandstone doorways and lintels, while the outer wall is also built with laterite bocks. Outside the compound in the northeast corner is the pond. The monument is Khmer style and currently in relatively good condition. The carvings on the lintels show that by this time there was conversion to Mahayana Buddhism.
