Tháp Bằng An, also known as Bằng An Tower, is a historical site located in Quảng Nam. The tower is an ancient Cham temple, built around the 9th to 10th centuries during the Champa Kingdom's rule. The architecture is notable for its octagonal structure. Made of bricks, it was originally a Hindu temple dedicated to Lord Shiva, reflecting the Cham people's religious and cultural practices at the time.
