Thien Mu Pagoda is a historic temple in the city of Hue. Its Tu Nhan Tower (now Phuroc Duyen Tower) was built in 1844 with seven storeys and is the tallest in Vietnam (21 m; 69 ft). Each of the seven storeys is dedicated to a different Buddha. The pagoda, about 3 km (2 mi) from the citadel in Hue on the northern bank of the Perfume River, is often regarded as the unofficial symbol of the city. The first temple on the site was built in 1601.
