Po Sah Inu Cham Towers are among the important surviving remnants of the ancient Champa civilization in the Phan Thiet area. Constructed between the late 8th and early 9th centuries, the complex originally served Hindu religious practices, particularly the worship of Shiva. Its architecture reflects the Hoa Lai style, one of the distinctive artistic traditions of early Cham temple construction.

The complex consists of three surviving brick towers of different sizes. The main tower features an altar associated with the linga and yoni, symbols linked to Shiva and concepts of creation and fertility in Hindu tradition. The towers’ carefully arranged brickwork, arched entrances and carved details demonstrate the craftsmanship and religious beliefs of the Cham people.

Beyond their architectural value, the towers remain connected to the spiritual life of the local Cham community. Traditional ceremonies and cultural activities, particularly those associated with the Kate festival, continue to take place at the site. Perched on Ba Nai Hill, the complex also provides a historical perspective on the region’s cultural landscape, complementing the coastal scenery and modern resort areas around Phan Thiet and Mui Ne.
