Get to know more about the Imperial Citadel of Thang Long

The Imperial Citadel of Thang Long stands as a monumental testament to Vietnam's extraordinary political continuity, having served as the seat of power for an unprecedented 13 consecutive centuries. This UNESCO World Heritage Site, inscribed in 2010, represents far more than ancient ruins - it embodies the very foundation of Vietnamese statehood and cultural identity.

Located in the heart of modern Hanoi, this archaeological marvel spans 18,395 square meters and reveals layers of history from the 7th to 19th centuries. Established in 1010 by Emperor Ly Thai To, the Imperial Citadel was built upon the foundations of a former Chinese fortress dating back to the 7th century, transforming from a defensive outpost into the magnificent center of Vietnamese imperial power.

What makes Thang Long truly extraordinary is its continuous role as a political hub through multiple dynasties - serving as the capital of Dai Viet under the Ly, Tran, and Le dynasties from the 11th to the 18th centuries. The name "Thang Long," meaning "Rising Dragon," was chosen after King Ly Thai To saw a golden dragon ascending in the sky, symbolizing the ascendance of Vietnamese independence and cultural sovereignty.

The World Heritage Site comprises two sections: the archaeological site at 18 Hoang Dieu Street and the central axis of the Nguyen Dynasty's Citadel of Hanoi, which together create an integrated heritage complex.

Since systematic excavations began in 2002, archaeologists have uncovered millions of artifacts, palace foundations, ancient roads, and countless treasures that provide unprecedented insight into Vietnamese imperial life and urban planning across more than a millennium.

The significance of the Imperial Citadel of Thang Long

1. Historical meaning: When the Ly dynasty built Thang Long in 1010 AD on the site of the former northern protectorate at Dai La, they were not only building a capital but also declaring the firm independence of Vietnam. This bold architectural act transformed a site that had once been a symbol of foreign domination into the magnificent heart of the newly independent Dai Viet kingdom. Each stone laid was an act of sovereignty, each courtyard a tribute to independence.

2. Architectural evolution: The citadel's architecture tells a captivating story of Vietnamese artistic evolution across centuries, through three dynastic styles. The citadel's architecture reveals Vietnam's transformation through its evolving dragon motifs: gentle Ly Dynasty dragons nestled in lotus petals reflected Buddhist peace, while victorious Tran Dynasty dragons grew fierce with five sharp claws after defeating Mongol invasions, and finally Le Dynasty dragons became formally majestic in Confucian restraint, carved alongside golden-glazed wooden beams and blue-green glazed tiles that created the classic Vietnamese imperial color palette. Most intriguingly, archaeologists discovered unique "hexagonal tower" foundations - six circular bases arranged around central squares - creating pleasure pavilions where emperors once contemplated their realm.

3. UNESCO Recognition: The site is one of the ten special national heritage sites proclaimed by the Prime Minister in 2009 and was inscribed on the World Heritage List by UNESCO's World Heritage Committee in 2010. Its Outstanding Universal Values are reflected in its historical longevity, its continuous role as a seat of power, and its multiple cultural layers

Let’s explore the Imperial Citadel of Thang Long

Doan Mon (The Southern Gate)

The Doan Mon is the southern entrance to the imperial palace and one of the best-preserved structures in the complex. This grand gate, constructed from layered stone and brick, served as the principal entryway for the emperor and high-ranking officials. It features five arched entrances, with the central passage reserved exclusively for the monarch. Above the main entrance, the words "Doan Mon" are carved on a stone plaque, marking its historical significance as a royal entrance.

Hanoi Flag Tower

One of Hanoi's most recognizable landmarks, the Hanoi Flag Tower, was constructed in 1812 during the Nguyễn dynasty as a military watchtower. Standing at 33.4 meters high, it comprises three tiers, each progressively smaller, leading up to the octagonal tower where the Vietnamese flag is proudly displayed. The tower was one of the few structures in Hanoi to survive French colonial destruction, making it a rare and significant relic.

Kinh Thien Palace Foundation

The Kinh Thien Palace was the political and spiritual heart of the Imperial Citadel, where emperors held court, conducted ceremonies, and managed state affairs. Though the original structure was largely destroyed during the colonial period, the remaining stone foundation and staircase provide a glimpse into its former grandeur. The large dragon-carved steps, adorned with intricate motifs, reflect the royal symbolism and craftsmanship of the Le dynasty.

Northern Gate (Cua Bac)

The Cua Bac (Northern Gate) is a historic structure that still bears battle scars from the French invasion in the 19th century. This massive brick and stone gate once served as a critical defensive structure, protecting the citadel from northern invasions. Visitors can still see cannonball marks on its walls, testifying to its resilience.

Revolutionary History: D67 House

During the Vietnam War, the D67 House served as the headquarters for the Central Military Commission and General Staff of the Vietnam People's Army. This secretive underground bunker played a crucial role in planning key military campaigns, including the Tet Offensive of 1968. Recent 2025 visitors particularly praise this section, noting "what we found most fascinating were the military bunkers used by the North Vietnamese during the Vietnam/American War. It's as if they've just stepped out of the room".

Behind the innocuous name "Hoa Lo," which translates to "fiery furnace," lies one of Vietnam's most emotionally charged historical sites. Originally constructed by French colonial authorities in 1896 to house Vietnamese political prisoners fighting for independence, this fortress-like structure later gained international notoriety as the "Hanoi Hilton" during the Vietnam War, where American prisoners of war were held.
