Stepping into the Imperial Citadel of Thăng Long feels like walking through the heartbeat of Hanoi’s thousand-year history. While it may not have the imposing grandeur of the Huế Imperial City, the Thăng Long Citadel holds a quiet majesty of its own — a living chronicle of Vietnam’s dynastic legacy, military triumphs, and cultural evolution. In 2010, UNESCO recognized it as a World Heritage Site, coinciding with Hanoi’s 1000th anniversary — a milestone that forever sealed its place among Vietnam’s greatest treasures.

🏰 A Legacy Carved Through Centuries

The Thăng Long Citadel stands on a site that has witnessed more than 13 centuries of transformation. Originally built by the Chinese Tang Dynasty in the 8th century, it was later expanded by Vietnamese kings, evolving into the political and cultural heart of Đại Việt (ancient Vietnam).

In 1010, Emperor Lý Thái Tổ moved the capital from Hoa Lư (Ninh Bình) to Thăng Long — meaning “Ascending Dragon” — believing this location symbolized prosperity and longevity. Over successive dynasties — Trần, Lê, Mạc, and Nguyễn — the citadel grew into a sprawling complex of palaces, gardens, and temples that reflected the empire’s might.

Sadly, much of it was destroyed in the 19th century when the French colonial forces razed many royal buildings to make way for administrative offices. Yet, what remains today — covering roughly 12 acres — is still enough to fascinate historians, travelers, and photographers alike.

🌸 Exploring the Central Sector – Where Kings Once Walked

Access to the Central Sector of the Citadel is now through a new southern entrance near Đoan Môn Gate, an imposing wall crowned by a double-roofed pavilion and pierced by five grand arches. This was once the main gate to the royal enclosure, where only kings, nobles, and high-ranking officials could enter.

Right inside, you’ll find the remnants of an ancient irrigation system unearthed during excavations — a subtle yet powerful reminder of how advanced Thăng Long’s early urban planning was.

🐉 Kinh Thiên Palace – The Heart of the Citadel

At the citadel’s center once stood the Kinh Thiên Palace, the grandest and most sacred structure of the entire royal compound. Though the palace itself no longer survives, its stone steps guarded by two magnificent dragon carvings remain. These Ly dynasty stone dragons — their bodies curling in graceful S-shapes — are regarded as some of Vietnam’s most exquisite examples of early royal sculpture.

Standing before them, one can almost imagine the ceremonies that once took place here — kings addressing their court, royal processions crossing the courtyard, and the sound of drums echoing through the halls.

🪖 The D67 Building – From Ancient Empire to Modern Warfare

Amidst ancient ruins, a surprising relic from the 20th century appears: the D67 Building, constructed in 1967 during the American War. Once a top-secret military headquarters, it served as the command center for the North Vietnamese Army, led by legendary General Võ Nguyên Giáp and Defense Minister Văn Tiến Dũng.

Inside, the atmosphere is frozen in time — conference tables still bear nameplates, and maps line the walls, outlining strategies that would eventually lead to Vietnam’s reunification in 1975. Beneath the building, a reinforced underground bunker reminds visitors of the era’s tension and the ever-present threat of aerial bombings.

For history buffs, this unexpected transition from dynastic grandeur to revolutionary resilience captures Vietnam’s layered past like no other site in the country.

🌺 Hau Lau Pavilion – The “Princess House”

Further north lies the Hậu Lâu, or “Rear Pavilion” — sometimes romantically called the Princess Pavilion. This elegant structure blends Eastern architectural symmetry with French colonial elements, a reflection of the shifting cultural tides in late 19th-century Hanoi.

It’s said that this was where Nguyễn dynasty concubines and princesses once resided during their stays in the capital. The pavilion today serves as a quiet exhibit space and photography spot, shaded by ancient trees and infused with the delicate scent of incense from nearby temples.

⚱️ The Archaeological Site – Where History Is Still Being Unearthed

Once you’ve explored the main citadel complex, step across Hoàng Diệu Street to visit the archaeological excavation site, an area that continues to reveal secrets buried for centuries.

Discovered in 2002, during construction work for Vietnam’s new National Assembly building, this massive site unearthed foundations of palaces, ceramic tiles, wells, and relics from multiple dynasties — from Lý to Lê and Nguyễn.

Many artifacts, including royal ceramics and architectural fragments, have been transferred to the Vietnam National Museum of History, but several remain displayed on-site in open-air pavilions.

Recent upgrades in 2024–2025 have improved visitor facilities, with interactive AR screens showing digital reconstructions of how the citadel might have looked in its prime. It’s an inspiring example of how modern technology helps revive lost history.
