A dome-shaped home is a type of dwelling that has a curved roof, usually made of concrete or metal. The two most common examples of this type of home are the igloo and the wigwam. An igloo is a type of shelter built from blocks of snow, traditionally used by the Inuit people of the Arctic region. A wigwam is a type of shelter made of wooden poles and covered with animal skins or woven mats, traditionally used by Native American tribes.
