Poshanu Towers, 7 km to the North East of Phan Thiet City, are
located on Ong Hoang (Mr. Heaven) Hill. Built by the Cham people in the
late 8th century, this group of towers worships the Shiva Genie, who is
highly respected by the Cham.
Beside these three towers, there was once a temple, but it has been buried in the ground for more than 300 years. Inside the main tower, there is an altar, on which a couple of Liga-Yoni, a symbol of the existence of the Shiva Genie, is worshipped.
