紹治帝
Emperor Thiệu Trị, who succeeded Minh Mạng, erected the Từ Nhân Tower in 1844, which is now known as the Phước Duyên tower. The brick tower stands 21 m and is of octagonal shape and has seven stories, each of which is dedicated to a different Buddha. The tower has stood there since, overlooking the Perfume River, and has become synonymous with the landscape of Huế and the Perfume River. Its impact is such that it has become the unofficial symbol of the city.
