The seat of Vietnamese power for something close to a thousand years, on the same ground, from the Ly dynasty in 1010 through to the war room from which the north ran the American war. UNESCO listed it in 2010 for exactly that continuity.
Above ground: Doan Mon, the great five-arched gate, and the flag tower of 1812. Below it, across the road at 18 Hoang Dieu, an excavation that keeps producing foundations, wells and ceramics from every one of those layers. Behind them, D67 — the concrete command bunker, left with its maps and its telephones on the table.
What it costs
Ticketed, with one fee covering the citadel and the archaeological site opposite. It is one of the better-value admissions in the city because of how much ground it covers.
When to go
Mornings, and allow more time than you think — most people give it forty minutes and miss the bunker entirely. ⚠️ Parts of the site close for excavation without notice.
Getting there
Fifteen minutes’ walk north of the Temple of Literature, twenty minutes west of the Old Quarter. Ba Dinh Square is ten minutes further west again.
If you only have an hour
Doan Mon, up onto the gate for the view down the axis, then straight to D67 in the gardens behind. The bunker is the thing you will still be thinking about later.
What people get wrong
⚠️ Most visitors never cross the road. The excavation at 18 Hoang Dieu is included in the same ticket and is where the thousand years is actually visible.
Nearby
Admissions, closing days and dress rules as published and checked on 7 September 2026. These change without much warning — confirm with the place itself before you travel. More sights, and how they fit together, in Landmarks & Sights.
