via Vietnam Plus, 30 January 2023: The Son Tay Citadel was built during the reign of Minh Mang, at a time when ramparts were being constructed in the backdrop of colonisation.
The Son Tay ancient fortress citadel, covering 16 ha in Son Tay township 40km from Hanoi’s centre, not only bears historic value, but also catches attention for its unique architecture. The site marked its 200 years of existence last year.
According to historical documents, Son Tay Citadel was built in 1822 during the reign of Minh Mang Emperor (1791-1841) under the Nguyen Dynasty. It was built entirely of laterite, a material that meets the requirements of a defensive building and was available in the locality.
