The Ho Citadel or Citadel of the Ho Dynasty(Vietnamese:Thanh nha Ho) is located in the Thanh Hoa Province in Vietnam’s north central coast region, approximately 150 km south of Hanoi. It was the capital of Vietnam from 1397 to 1407 during the short-lived Ho Dynasty. The site was inscribed as a cultural heritage site by UNESCO in 2011.
Measuring 877 x 889m, the citadel is marked by an enclosing wall of stone, which still remains standing. The enclosure has a diameter of over 3,500 m, with a wall height of 5-6 m. Unlike other citadels in the country that were constructed with brick, construction of the Ho Citadel employed massive stone slabs sourced from nearby mountains.
The stone materials used for construction were carefully hewn into slabs with uniform dimensions, and the citadel was marked by four arched gates (South, North, East, and West). Researchers are currently exploring how the stone walls were constructed.
