Behind Kroul Romeas Group, there were four more sanctuaries made of brick and built during the reign King Suryavarman 1(end of 11th century). These sanctuaries were built on a rectangular hill, and faced to the East. One of sanctuaries was not completely built yet, it was likely built in later period. The lintel was carved in the form of bow without the modal. At the southeastern side, there were two temples recognized as the original ancient khmer styles.
