The ancient castle of tulou in Fujian Province. These unique buildings, called tulow, began to appear during the Tang Dynasty, in the 10th century, when Hakka people were forced to migrate to southern China and defend themselves from the local population.</p>

This tuloe was built in the 12th century. It represents four buildings of round shape and several square. In fact, the buildings are a fortress that has only one entrance. The main fortress wall was built of a mixture of bamboo, earth, stone, granite, wood and other improvised materials. Until the middle of the last century, these structures were used for their intended purpose. This year there will be five years from the date of the inclusion of 46 Toulou in the UNESCO List of Protected Areas.
