Fujian Tulou is a type of Chinese rural dwellings¬†of the¬†Hakka¬†in the mountainous areas in southeastern Fujian, China. They were mostly built between the 12th and 20th centuries. A tulou is usually a large, enclosed and fortified earth building, mostly in square or circle, with very thick load-bearing¬†rammed earth¬†walls. It can be three to five-storied and can house about 80 families. The fortified outer structures are built with compacting earth, mixed with stone, bamboo, wood and other readily available materials. The walls can be up to 6 feet (1.8¬†m) thick. Fujian Tulou¬†is the official name adopted by UNESCO for all dwellings of this type.
The Tianluokeng Tulou Cluster is the most famous one among the Fujian Tulou sites. It is located in Shuyang Town of Nanjing County, Fujian province. The cluster consists of one square tulou (Buyun Building), three circular tulous (Zhenchang Building, Ruiyun Building, Hechang Building) and one oval tulou (Wenchang Building). The five buildings stand in a straight row along the mountain, forming a wonderful picture..
There are more than 20,000 tulous in Fujian, mostly in the mountainous regions of¬†Yongding County of¬†Longyan¬†City and¬†Nanjing County¬†of¬†Zhangzhou City.¬†As the Tulous are scattered among the villages, one has to charter a van or ride a motorbike to get round the villages. Tulou can be visited anytime of the year though it is probably prettier in spring and autumn.
