House Type - Fujian Tulou

Fujian Tulou (simplified Chinese: 福建土楼; traditional Chinese: 福建土樓; pinyin: Fújiàn Tǔlóu, "Fujian earthen structures") is a type of Chinese rural dwellings of the Hakka is in the mountainous areas in southeastern Fujian, China. They were mostly built between the 12th and the 20th centuries.

A tulou is usually a large, enclosed and fortified earth building, most commonly rectangular or circular in configuration, with very thick load-bearing rammed earth walls between three and five stories high and housing up to 80 families. Smaller interior buildings are often enclosed by these huge peripheral walls which can contain halls, storehouses, wells and living areas, the whole structure resembling a small fortified city.
