The Unfinished Pagoda, also known as the Thien Mu Pagoda, is an iconic symbol of Hue city in central Vietnam. It is a seven-story octagonal pagoda located on a hill overlooking the Perfume River. The pagoda was built in 1601 during the reign of Emperor Nguyen Hoang and was expanded in the 18th and 19th centuries.

The pagoda has become a symbol of Buddhist architecture in Vietnam and attracts visitors from all over the world. Each level of the pagoda represents a different Buddha, and the top level is said to hold the ashes of the monk who founded the pagoda. The pagoda's architecture is typical of Buddhist pagodas in Vietnam, with a distinctive Chinese influence.

The Unfinished Pagoda is also known for its association with the monk Thich Quang Duc, who burned himself to death in 1963 in Saigon to protest the persecution of Buddhists by the South Vietnamese government. A car used by Thich Quang Duc during his self-immolation is on display at the pagoda.

Visitors to the Unfinished Pagoda can climb the stairs to the top level for a panoramic view of Hue and the Perfume River. The pagoda is also home to a small museum displaying artifacts related to Buddhism and the history of the pagoda.
