This tower, also known as the "Copper Tower", standing gracefully on top of a small hill, is all that remains of the Cha Ban citadel, the last capital of the Cham people. Built in the early 13C, it shows the hallmarks of the style of My Son, and has preserved some fine sandstone decoration, such as the four sculpted pilasters around the body of the tower, the flame shaped antefixes, and small towers on the corner of the roof. Sadly, part of the building has been restored with cement.
