Located in a suburb of Quy Nhơn just three kilometres north of the city centre, the Hưng Thạnh or Twin Towers were constructed in the late 12th-early 13th century as part of a larger group. Of square design with false doors, pilasters and other decorative elements typical of the traditional Chăm tower, the structures belong architecturally to the Bình Định style but are notable for their curved pyramidal roofs, which indicate artistic influence from Angkor. The Hưng Thạnh Towers underwent extensive restoration in 1996.
