Citadel of the Hồ Dynasty (Template:Lang-vi, Hán Nôm: 城家胡; also called Tây Đô castle or Tây Giai castle) is a 15th century stone fortress in Thanh Hóa, Vietnam. It served as the Western Capital of the Hồ Dynasty (1400-1407).

It is located in Tây Giai commune, Vĩnh Lộc District, in Thanh Hóa Province, in Vietnam's North Central Coast region.

Tây Đô castle is rectangular in shape. Its north-south side is 870.5 m (2,856 ft) in length and its east-west side is 883.5 m (2,899 ft) in length. There are four gates: one at the south (fore gate), one at the north (back gate), one at the east (left gate), and one at the west (right gate). The southern gate is 9.5 m (31 ft) high and 15.17 m (49.8 ft) wide.

The castle was constructed from stone blocks, each of which is 2×1×0.7 m (6.6×3.3×2.3 ft) size on average.

Except for its gates, the castle is mostly ruined.

The Citadel was inscribed on UNESCO World Heritage Sites on June 27, 2011.^[1]
