The Fujian Tulou are remarkable examples of rural dwellings in the mountainous regions of southeastern China, specifically in Fujian province. These large, enclosed, and fortified structures, unique to the Hakka people, were constructed between the 12th and 20th centuries. Recognized for their cultural significance and unique architectural design, the Fujian Tulou were inscribed as a UNESCO World Heritage Site in 2008. These earthen buildings, often circular or rectangular, provided communal living spaces that were ingeniously designed to be self-sufficient and protective against invaders.
