Hue Citadel (;
chữ Hán: 京城) was surveyed by Emperor Gia Long in 1803 and the construction began in 1805 and was completed in 1832 under the reign of emperor Minh Mang. In the history of modern Vietnam, the construction of Hue Citadel was regarded as the most massive and large-scale project with tens of thousands of people participating in the construction, millions of cubic meters of earth and rock and huge amount of work like digging trenches, rivers, site clearance, building walls... lasting for 30 years under two first emperor. Only emperor and his family was allowed to reside in the citadel while commoners was banned to enter except court ladies, eunuchs and soldiers served inside the palace. Besides that, officials and students of imperial academy were allowed to enter the citadel and had to exit after working hours. During French occupation, French colonial government establish their

Vauban style fortification. Immediately after ascending the throne,
Gia Long conducted a survey to select a location to build a new citadel. Finally, he chose a large area on the north bank of the
Perfume River, including the land of the villages of Phu Xuan, Van Xuan, Dien Phai, An Van, An Hoa, An My, An Bao, The Lai, and part of the two rivers Bach Yen and Kim Long as the place to build the citadel. In terms of
feng shui, the front of the citadel is

Outer Citadel (Ngoại Thành, 外城) Phu Văn Pavilion Phu Văn lâu (敷文樓) is the two-story pavilion facing south located in front of the Flag Tower looking out to the Perfume River. Pavilion was built in the year of the 1819 before imperial examination event by emperor Gia Long, used as a place to display important edicts of the emperor and the court or the results of

Inner citadel (Nội Thành, 內城) Flag tower In the middle of the front of the Citadel is a large flag pole called
Kỳ Đài (旗臺), built in the 6th year of Gia Long (1807). During the reign of emperor Minh Mang, the flagpole was renovated in 1829, 1831 and 1840. The flagpole consists of two parts: the base and the flagpole. The base consists of three rectangular truncated pyramidal floors stacked on top of each other. The first floor is over 5.5 m high, the middle floor is about 6 m high, and the top floor is over 6 m high. The total height of the three floors is about 17.5 m. From the ground to the lower floor is a small path on the left side of the flagpole. The lower floor is connected to the middle floor by a 4 m wide arched door, the middle floor is connected to the top floor by a 2 m wide arched door. The top of each floor has a 1 m high railing system decorated with hollow-cast bricks. The three-storey foundation is paved with square bricks and bricks and there is a rainwater drainage system below. Previously, there were two watchtowers and eight cannons. The original flagpole was made of wood, with two floors and was nearly 30 m high. In the sixth year of emperor Thieu Tri (1846), the flagpole was replaced by a longer wooden pole over 32 m long. In the sixteenth year of Thanh Thai (1904), this flagpole was damaged by a heavy typhoon, so it was replaced with a cast iron pipe. In 1947, when the French army reoccupied Hue, the flagpole was broken by artillery fire again. In 1948, the current reinforced concrete flagpole built with a total height of 37 m. During the Nguyen Dynasty, Emperor's banner was raised on all occasions of ceremonies, celebrations, tours and even emergency announcement. On top of the flagpole, there was also an observation post called Vọng Đẩu. Occasionally, guards had to climb up Vọng Đẩu and use a telescope to observe the coast. On August 23, 1945, after Bao Dai abdicated, the red flag with yellow star of the Democratic Republic of Vietnam replaced the flag of the Nguyen Dynasty.
Nine imperial grand cannons Nine grand cannons (;
chữ Hán: 九位神攻) was created by Hue artisans in the second year of Gia Long (1803). These nine cannons are considered the largest in Vietnam and one of the most valuable bronze works of art. The Nine Cannons were originally placed at the front of the Imperial palace. In 1917, during the reign of Khải Định, these cannons were moved to the current position. In 2012, the Nine Cannons were recognized as a National Treasure of Vietnam. After defeating the
Tây Sơn Dynasty in 1802, Emperor Gia Long ordered the collection of all bronze weapons and objects to cast nine cannons standing for his glorious victory. The casting work officially began on 31 January 1803 (Gia Long 2nd year) and was supervised by four people: Commander Nguyễn Văn Khiêm, Chief Commander Hoàng Văn Cẩn, Deputy Commander Ích Văn Hiếu (some document record his name as Cái Văn Hiếu) and Deputy Minister of Public Works Phan Tấn Cẩn. In order to successfully cast these nine cannons, emperor Gia Long carefully selected the most outstanding people, not only in professional qualifications but also possessing noble virtues. The casting of all nine cannons was completed by the end of December 1804. File:Cửu vị thần công 2.JPG|Pattern engraved in cannon. File:Họa tiết súng thần công.jpg|Pattern engraved in cannon. File:Cửu vị thần công1 .jpg|Four cannons named "Spring, Summer, Autumn, Winter" in the current position. File:Nine Holy Cannons of Nguyen Dynasty.JPG|The five cannons named "Metal, Wood, Water, Fire, and Earth" at current position. In the 15th year of Gia Long (1816), emperor bestowed the title of "Invincible General of the Gods" on all nine cannons. The title and content of edicts were engraved directly on the body of each cannon. Each cannon was meticulously carved with its title, rank, weight, cannon usage instruction, an account of the battles with the Tay Son dynasty and the collection process of bronze to cast the cannons. The court assigned military officers to regularly guard these nine cannons, and the emperor often held solemn ceremonies to worship the Nine Divine Cannons. Since 1886, under emperor Dong Khanh, the court abolished this worship, but the guards still often worshiped themselves. These cannons are named after the four seasons and the
five elements in the order of "Spring (Xuân, 春)" - "Summer (Hạ, 夏)" - "Autumn (Thu, 秋)" - "Winter (Đông, 冬)" - "Wood (Mộc, 木)" - "Fire (Hỏa, 火)" - "Earth (Thổ, 土)" - "Metal (Kim, 金)" - "Water (Thủy, 水)". The name of each cannon is embossed on the knob at the end of each gun.

The system was finalised in 1836 under emperor Ming Mạng. Initially, Tôn Nhơn phủ was only a place to keep records, but later this agency also had the authority to resolve issues related to the imperial members, princes and grandsons in the imperial family. During the French colonial period from 1897, the council was under the direct control of the Resident-Superior of Annam. After the fall of Nguyen Dynasty, the council had no any reason to exist, then it was changed the name to clan organization called "
Nguyễn Phúc Clan Council" under the direct advice of former empress dowager
