A wigwam, wickiup or wetu is a domed dwelling formerly used by certain Native American and First Nations tribes.The domed, round shelter was used by many different Native American cultures. The curved surfaces make it an ideal shelter for all kinds of conditions. The structures are formed with a frame of arched poles, most often wooden, which are covered with some sort of roofing material. Some of the roofing materials used include grass, brush, bark, rushes, mats, reeds, hides or cloth. Men built the wigwams and the women put on the coverings..Details of construction vary with the culture and local availability of materials.A typical wigwam in the Northeast had a curved surface which can hold up against the worst weather.A longhouse or long house is a type of long, proportionately narrow, single-room building built by peoples in various parts of the world including Asia, Europe, and North America. Many were built from timber and often represent the earliest form of permanent structure in many cultures.The Iroquois (Haudenosaunee or "People of the Longhouses") who resided in the Northeastern United States as well as Eastern Ontario and Quebec, canada,built and inhabited longhouses. These were sometimes more than 246 ft in length but generally around 5 to 7 m 16 to 23 ft wide.The roof is made by bending a series of poles, resulting in an arc-shaped roof. The frame is covered by bark that is sewn in place and layered as shingles, and reinforced by light swag some are covered with leaves and grasses.
