A tulou is a unique architecture found only in the mountainous areas bordering Fujian and Guangdong in southern China. The "Earth building" is an enclosed buildings, usually square or circular in shape, with a very thick earth wall (up to 6 feet thick) and wooden skeletons, from three to five storeys high, housing up to 80 families. These earth buildings have only one entrance, guarded by 4–5-inch-thick (100–130 mm) wooden doors re-enforced with an outer shell of iron plate. The top level of these earth building have gun holes for defence against bandits. In spite of the earth wall, some of them are more than 700 years old, surviving thru centuries of natural elements, including earthquakes, yet still standing solid. It was listed as world cultural heritage in 2008.
