The Wanshan tribal community is located in Maolin District, Kaohsiung, and formerly known as “mandaulan;” a name that remained in use throughout Japanese rule, when the community relocated to Wanshan village in 1956. In addition to unique characteristics in traditional ceremonies, fishery, hunting, language, and culture, the most distinctive feature of the village is a sunken stone slab house built using ancient techniques. One third of the sunken stone slab house is below ground, so visitors have to bend down when entering. In addition to living considerations, this also prevents intruders from directly entering the building and thereby protects its inhabitants. It is also easier to chop off the heads of intruders in a bent position. The house was constructed by piling stone slabs to form external walls after excavating the pit. The outermost layer of the structure is made of wood and larger stone slabs. A constant temperature is maintained throughout the year with rock insulation; therefore, the interior serves as a highly comfortable living space that is warm in winter and cool in summer.
