The Central Sector of the Imperial Citadel of Thang Long became a UNESCO World Heritage Site in 2010, and its history as a seat of power spans thirteen centuries. King Ly Thai To established the capital at Thang Long in 1010; successive dynasties built and altered the citadel, which housed Vietnamese kings and hosted royal ceremonies. Today, walking through its gates and excavation areas connects you directly to Vietnam’s imperial past. This complete Imperial Citadel Thang Long guide for 2026 covers history, what to see, ticket info, and how to plan your visit. Hanoi merged its districts into wards on 1 July 2025; this guide keeps the old district names because they are still how most people and maps describe the city.

About Thang Long Imperial Citadel

Thang Long (“Rising Dragon”) was the name King Ly Thai To gave to the new Vietnamese capital in 1010 AD. The citadel served as Vietnam’s political center under the Ly, Tran, Le and Mac dynasties; once the Nguyen dynasty established its capital at Hue in 1802, Thang Long became an important regional administrative center instead. Under French rule, most of the citadel was demolished to make way for offices and barracks. UNESCO declared it a World Heritage Site in 2010, citing 13 centuries of cultural heritage layers.
