Императорская цитадель

The Imperial City (Vietnamese: Hoàng thành; Hán tự: 皇城) is a walled enclosure within the citadel (Kinh thành; 京城) of the city of Huế, the former imperial capital of Vietnam.In June 1802 Nguyễn Ánh ascended the throne of a unified Vietnam and proclaimed himself Emperor Gia Long with Hue, the ancestral seat of the Nguyễn Lords as the capital. Geomancers were consulted as to the propitious location site for the new city and construction began in 1804. Thousands of workers were ordered to build the walled citadel and ringing moat, measuring some 10 kilometres (6.2 mi) long. The original earthwork was later reinforced and faced with brick and stone resulting in 2 m (6 ft 7 in)-thick ramparts.
