The Fujian tulou (Chinese: 福建土楼; literally: 'Fujian earthen buildings') are Chinese rural dwellings unique to the Hakka in the mountainous areas in southeastern Fujian, China. They were mostly built between the 12th and the 20th centuries.
Fujian's Hakka Tulou ('Earth Buildings' 土楼 Tǔlóu /too-loh/) are unique, usually round, fort-like buildings, built with a mixture of clay and sandy soil. These rare buildings were designed by the circumspect Hakka minority as large fortresses and apartment buildings in one, and were inscribed by UNESCO as a cluster of World Cultural Heritage Sites in 2008.
In the first trailer for Disney's lively action film Mulan (release date: March 27, 2020), Mulan's home is a Fujian tulou.
Because of their large, round shapes in clusters, tulou satellite images produced great speculation during the Cold War. They were even believed by Western countries to be China's nuclear missile silos!
History
Walled villages were built from the Song Dynasty (960–1279), when the Hakka Han moved from their original homeland in northern central China to the mountains of southeast China.
From then construction remained much the same, until conflicts with neighbors led to the development of fort-like housing from the Ming Dynasty (1368–1644) to the Republic of China era (1912–1949).
Today, the earth buildings are one of Fujian Province's top tourist attractions, and most of the residents are involved in tourism, instead of farming.
