Citadel of the Ho Dynasty

Built in 1397 as a new capital, the citadel served as a seat of power for only a few years but left one of the most impressive pieces of stone engineering in Southeast Asia. Blocks of limestone, some of them enormous, were cut and laid without mortar into walls forming a rectangle nearly nine hundred metres on a side, with an arched gate at each compass point. The south gate is the largest, three arches deep beneath a stepped parapet. Inside there is almost nothing: rice fields, a couple of farm tracks, scattered column bases and stone dragons from vanished halls. A small museum near the gate displays excavated tiles, ceramics and carved stone.

What's there

• The south gate - three stone arches under a stepped parapet, the best preserved of the four.
• The dry-laid walls - huge limestone blocks fitted without mortar, still standing after six centuries.
• The interior fields - farmland where the palaces stood, with column bases and carved dragons in the grass.
• The site museum - a small display of excavated tiles, ceramics and carved stone.

When to go

October to April is drier and cooler, since the site is completely open and brutal under a summer sun. Early morning or late afternoon gives better light on the stonework and a bearable temperature. A car or motorbike is essential, as the gates stand roughly a kilometre apart. Two hours covers the gates and the museum.

Practical notes

Almost nothing survives inside the walls, so a visit means four gates, a stretch of masonry and farmland, which can feel thin for the driving involved. There is no shade, no cafe worth the name and little interpretation beyond a few panels. Crops and buffalo occupy the interior, so walking the full circuit means farm tracks and mud after rain.
