Located on Ong Hoang (Mr. Heaven) Hill and built in the late 8th century, the Thap Poshanu Cham Tower worships god Shiva, who is highly venerated by the Cham. Beside these three towers there was once a temple, but it has been buried for more than 300 years. Inside the main tower is an altar, on which a couple of Liga-Yoni (a symbol of Shiva) is worshiped. The towers were repaired and upgraded from 1990 to 2000.
Fishermen living in the vicinity also come here to appeal for safe sea journeys before they go out to sea. The are sometimes refered to as the castle of the king and queen (or god and godess) of the sea. Much local folklore and legend has developed to regard the towers, since the time they were built by the ancient Cham people. the towers have served as an important landmark for fishermen and shipping vessels in navigation as well. It should be noted that on the same hill with the Cham temple complex is a former military stronghold from the recent war. While the Towers are safe to explore, we recommend visitors do not climb around the nearby fort due to the possibility of unexploded ordinance.
