The document summarizes the traditional Fujian Tulou dwellings in China. The Tulou are large, fortified earth buildings constructed between the 14th-16th centuries during the Ming Dynasty for defensive purposes. They could house up to 800 people around a central courtyard and had only one entrance above the first floor for security. The circular structures were built out of packed earth and wood, with small uniform rooms and communal spaces for activities like drying clothes and farming. By the 16th century, some Tulou grew to enormous sizes for defense against bandits and invaders during times of conflict.
