This is the history of Thang Long Imperial Citadel

The first foundations

The first foundation of the city was built in the 7th century, the Citadel was founded. During that time, Vietnam was being invaded by China, which built a fortress there. The capital was shifted from Ninh Binh (Hoa Lu) to Dai La (the former name for Hanoi) by King Ly Thai To in 1010. The citadel was constructed over the ruins of the fortress. Throughout the next 13 decades, the Citadel served as the political center of the region.

Under the Tran, Le, and Nguyen Dynasties, the Imperial Citadel suffered several wars that ravaged it. When Emperor Quang Trung relocated the Vietnamese capital to Phu Xuan (now Hue) in 1810, Thang Long was the capital. However, it was abandoned in the late 18th century when the capital was moved to Hue.

French colonial times

As a result of French colonial rule, many structures suffered severe damage. The majority of the remaining structures were destroyed by the end of the twentieth century. More than 4, 000 French colonial soldiers were imprisoned at the Citadel by Japanese force in 1945.

Vietnam War

During the Vietnam War, the Imperial Citadel of Thang Long in Hanoi was used as a military base by the Vietnamese People’s Army. The site was strategically important as it was located in the center of the city and provided a vantage point for observing American military activities. The citadel was heavily fortified with trenches, bunkers, and anti-aircraft guns to defend against possible air raids. The Vietnamese government also used the citadel as a storage facility for important documents and artifacts to protect them from being destroyed during the war. After the war, the citadel was restored and opened to the public as a historical and cultural site.

In 2010, the UNESCO World Heritage Committee listed the Central Sector on the UNESCO list of important sites for world heritage.

Kinh Thien Palace is one of the most significant and well-known structures in the Imperial Citadel of Thang Long. It was constructed during the Le Dynasty and was later restored during the Nguyen Dynasty. The palace served as the most important building in the citadel and was used for major events, including coronations and important state occasions.

The palace is divided into three main sections: the front, middle, and rear halls. The front hall was where the emperor received guests and held important meetings, while the middle hall was used for banquets and ceremonies. The rear hall was where the emperor lived and conducted his private affairs.

The palace was built in a unique architectural style with a combination of Chinese and Vietnamese elements. The roof of the palace is covered with yellow-glazed tiles, which symbolize the imperial power of the Vietnamese monarchs. The interior of the palace is decorated with intricate carvings and ornate details, such as dragon motifs and gold leafing.

Unfortunately, much of the original palace was destroyed during the French colonial period, and only a portion of the original structure remains today. However, efforts have been made to restore and preserve the remaining sections of the palace, making it an important historical landmark in Hanoi.

The Bac Mon Gate served as the main entrance to the Imperial Citadel of Thang Long, and only members of the royal family, high-ranking officials, and foreign dignitaries were allowed to enter through this gate.
