2. History of the Thang Long Citadel

The story of the Thang Long Citadel began in the 7th century, when it was first known as Dai La Citadel, built under the Tang Dynasty (An Nam Protectorate). Later, in the 9th century, it was rebuilt and expanded by Gao Pian, a Chinese governor, turning it into one of the strongest fortresses in northern Vietnam at that time.

In 1010, King Ly Thai To, the founder of the Ly Dynasty, moved the capital from Hoa Lu (Ninh Binh) to Dai La. As his royal boat entered the city, he saw a golden dragon rising into the sky. Believing it to be a good omen, he renamed the city “Thang Long”, meaning “Rising Dragon” - symbolizing strength, prosperity, and national pride.

From that moment, Thang Long became the political, cultural, and economic heart of Vietnam for more than eight centuries, through the Ly, Tran, Le, and Nguyen Dynasties.

The ancient capital was built with three main layers:

• La Thanh (Outer Wall) - the city wall protecting the capital and residents.
• Hoang Thanh (Imperial Citadel) - the administrative and royal working area.
• Tu Cam Thanh (Forbidden City) - the private residence of the emperor and royal family.

Throughout history, Thang Long underwent many changes. During the Tran Dynasty (13th-14th century) and Le Dynasty (15th-18th century), new palaces, temples, and royal structures were built. By the Nguyen Dynasty, the capital moved to Hue (1802), and Thang Long became known as Bac Thanh (Northern Citadel).

In 1882, when the French colonial army invaded Hanoi, most of the original citadel was demolished to build military barracks and government offices. Only a few key structures survived, such as Doan Mon Gate, Kinh Thien Palace foundation, Hau Lau (Princess’s Palace), and Bac Mon (Northern Gate).

Today, what remains of the Imperial Citadel of Thang Long Hanoi stands as a symbol of resilience and continuity. Beneath the surface, archaeological excavations at 18 Hoang Dieu Street have revealed layers of relics - ceramics, foundation stones, and ancient wells - that tell stories of over 1,300 years of continuous development.

Every stone, gate, and brick here holds the memory of Vietnam’s royal past - a story of kings and dynasties, of rises and rebuilds, and of a nation that has always stood tall through time.

3. Architecture of the Thang Long Citadel

What makes the architecture of Thang Long Citadel so unique?

The architecture of Thang Long Citadel combines Vietnamese royal design, Confucian harmony, and Southeast Asian elegance. It reflects balance, respect for nature, and the artistry of Vietnamese culture.

In traditional royal architecture, buildings face south to welcome prosperity and peace. The layout follows Confucian principles of symmetry and moral order, while curved roofs, dragon and phoenix carvings, and open courtyards show the creative touch of Southeast Asian art.

Main attractions include:

• Doan Mon Gate - the main southern entrance to the royal palace.
• Kinh Thien Palace - once the ceremonial center where emperors held royal audiences.
• Hau Lau (Princess Pavilion) - a peaceful residence for royal women and concubines.
• Bac Mon Gate - the only city gate still standing from the Nguyen Dynasty era.
• Flag Tower of Hanoi - built in 1812, one of the few structures that survived the French destruction, now a proud symbol of the city.

Each structure reflects the grandeur and precision of ancient Vietnamese craftsmanship, symbolizing both political authority and cultural depth.

Fun Fact: When the Kinh Thien Palace was excavated, archaeologists found stone dragons with gentle faces and soft lines, unlike the fierce dragons in Chinese art. This shows how Vietnamese kings valued grace and peace over power - a unique trait that makes Thang Long’s architecture stand out in Southeast Asia.

4. Role of Thang Long Citadel

For over 1,000 years, the role of Imperial Citadel of Thang Long has been the political and cultural center of Vietnam. This was where emperors ruled, royal ceremonies took place, and key decisions that shaped the nation’s destiny were made.

Beyond politics, the citadel was also a symbol of royal culture - preserving classical Vietnamese architecture, art, Confucian traditions, and spiritual values that deeply influenced the country’s identity.

Because of its central importance, people from across the kingdom came to live, trade, and work around the citadel. Over time, this area developed into the famous Hanoi Old Quarter, where each street specialized in a unique craft - from silk and silver to herbal medicine.

Today, travelers can explore both the Imperial Citadel and the Old Quarter to experience how ancient history and modern life blend seamlessly in the heart of Hanoi. This connection between past and present is what makes Hanoi and Vietnam - truly special.

5. Thang Long Citadel UNESCO Heritage Recognition

In 2010, the Imperial Citadel of Thang Long - Hanoi was proudly inscribed as a UNESCO World Heritage Site. This event marks a thousand years since King Ly Thai To established the capital in 1010.

This global recognition honors the citadel’s unbroken history, unique architecture, and profound cultural influence across Asia. Thang Long is one of the rare heritage sites worldwide that shows continuous urban development spanning from the 7th to the 19th century - a living timeline of Vietnam’s evolution through dynasties and colonial eras.

Archaeological excavations here have uncovered ancient palaces, pottery, royal seals, and drainage systems, all offering invaluable insight into Vietnam’s imperial legacy.

Together with other UNESCO World Heritage Sites in Vietnam such as Hue Imperial Citadel, Hoi An Ancient Town, My Son Sanctuary, and Ha Long Bay - the Imperial Citadel of Thang Long forms a vital chapter in Vietnam’s story, connecting the nation’s royal past with its vibrant present.
