The Cham King Jaya Simhavarman III (Viet: Chê Mân) is credited with constructing the tower in honor of Po Klaung Garai toward the end of the 13th century. However, the presence of several steles from an earlier period suggests that Jaya Simhavarman may merely have restored and added to structures that were already in place.[5]
An inscription, dated 1050, at Po Klong Garai commemorated the military victory of two Cham princes (presumably representing the northern dynasty of Indrapura headquartered near Mỹ Sơn) over the people of Panduranga in southern Champa. According to the inscription, the victorious princes celebrated by erecting two lingas and a victory column.[6]
