Thiệu Trị
During the period of the Nguyễn Dynasty in the 19th century, Emperor Thiệu Trị declared Diệu Đế Pagoda to be one of the national pagodas of Vietnam. The pagoda entrance is on the banks of the Dong Ba canal. The temple gates face southwest; directly on the other side of the canal is the Dong Ba gate of the eastern side of the Citadel of Huế, which was the imperial headquarters of the Nguyễn Dynasty, erected by Gia Long at the start of the 19th century.
