Built on a small hill overlooking the Song Huong (Perfume River), 4km southwest of the Citadel, this seven-storey pagoda is an icon of Vietnam and as potent a symbol of Hue as the Citadel. The 21m-high octagonal tower, Thap Phuoc Duyen, was constructed under the reign of Emperor Thieu Tri in 1844. Each of its storeys is dedicated to a manushi-buddha (a Buddha that appeared in human form).
Thien Mu Pagoda was originally founded in 1601 by Nguyen Hoang, governor of Thuan Hoa province. Over the centuries its buildings have been destroyed and rebuilt several times. Since the 1960s it has been a flashpoint of political demonstrations, with a notable moment coming in 1993, when a man arrived at the pagoda and, after leaving offerings, set himself alight chanting the word ‘Buddha’.
Beyond the pagoda tower is a gateway, on the upper floor of which sits an effigy of the Celestial Lady (Thien Mu) that the pagoda is named after. Above the central portal is a board with the Chinese characters 靈姥寺 (literally 'Divine Old Woman Temple'), in honour of the presiding deity of this plot of land.
The temple itself is a humble building in the inner courtyard, past the triple-gated entrance where three statues of Buddhist guardians stand at the alert. In the main sanctuary behind the bronze laughing Buddha are three statues: A Di Da, the Buddha of the Past; Thich Ca, the historical Buddha (Sakyamuni); and Di Lac Buddha, the Buddha of the Future.
Many sights around Hue, including Thien Mu Pagoda and several of the royal tombs, can be reached by boat via the Perfume River. Most hotels and travellers’ cafes offer shared day tours from US$5 to US$20 per person.
