The Qui Nhon Ban It Towers, a group of four towers better known as the Silver Towers, are one of the best surviving examples of late Cham architecture. The Cham kingdom of Champa flourished in south and central Vietnam from the second century onward and reached the height of its power during the 9th century.

Adopting Hiduism as their state religion, the Chams adapted architectural models from their Indian counterparts to crate something unique to Vietnam. This is best illustrated by the Kalan complex, of which the Silver Towers are a great example. The tem kalan refers to a min sanctuary tower centred on a single shrine, housing the main object of worship.

The hill was landscaped with steps, achieving an overall pyramidal effect and creating a temple-mountain. Constant warring took its toll on the Champa, and by the early 13th century they had been quashed by the Khmers of Cambodia.
