Prasat Sa Kamphaeng Yai in Sisaket Province was built in the 11th century as a shrine dedicated to the Hindu deity Shiva. During the 13th century it was converted for use as a Mahayana Buddhist temple. Three towers, aligned on a north–south axis and facing east, were set on a raised platform and enclosed within a sandstone and laterite gallery, while two additional towers, similarly aligned, would likely have been sited behind the main towers, an arrangement similar to that found at Prasat Muang Tham in Buriram Province. Only one of the rearmost two has been reconstructed, however, resulting in a present asymmetrical arrangement. Several nicely carved lintels and pediments remain, in various states of deterioration.
