福建土樓產(chǎn)生于宋元，成熟于明末、清代和民國時(shí)期。土樓以石為基，以生土為主要原料，分層交錯(cuò)夯筑，配上竹木作墻骨牽拉，丁字交叉處則用木定型錨固。2008年7月6日，福建土樓在加拿大魁北克城舉行的第32屆世界遺產(chǎn)大會上，被正式列入《世界遺產(chǎn)名錄》。

Hidden in the rolling mountains of the southeast Chinese province of Fujian is a series of giant multistoried homes built with wood and defended with mud walls.Mostly built between the 15th and 20th centuries,these shared homes purposefully nestle among tea,tobacco,rice fields and thick forests of pine and bamboo.

These structures are known as the Fujian Tulou.Throughout history,their residents have mostly been Hakka—migrants in southern China who originated from lands next to the Yellow River.Population pressure created conflicts between the Hakka and their neighbors,so they built their homes to double as fortification（防御）structures.

Walls are up to 5 feet thick and can reach 60 feet high.Defensive features include iron gates,underground escape tunnels,tiled roofs,a water well,and a backup stock of grains and livestock in the event of a lengthy conflict.The buildings,usually three to four stories,are symmetrical（對稱的）in their shapes—this means that in the event of a conflict there are no blind spots.

While tulou translates as“earthen building”in Chinese,the construction materials are made up of far more than just mud.The foundations of the structures are made of local river stones and the walls are made of fine mud sourced from rice fields.The mud is reinforced（加固）with bamboo mixed with sand and lime,and then compacted（壓實(shí)）with a thick stick.

While similar in layout,each tulou is unique.The Yuchang Building,built in 1308,is the oldest and tallest and known for its tilted pillars,some of which lean at a sharp 15-degree angle.The Hegui Building is the largest rectangular(矩形的）one,covering an area of nearly 1,300 square meters.The Chengqi Building is the most massive in size,with about 400 rooms.

Because of the economic draw of the neighboring cities,there's been a great loss of residents over the last 25 years.Today the structures that once housed thousands of people are only home to a couple of dozen permanent residents,most of them elderly.In 2008,46 structures were given World Heritage status by UNESCO.The growth of tourism in the area not only has kept the buildings from being destroyed,but also has promoted local businesses and allowed tulou to remain living and functional relics.
