An architectural dome is a curved element that forms the top half of a sphere. There is no need for internal support in domes, and a great deal of area can be covered with very little material. It is possible to build dome structures from a wide variety of materials, including the more common ones such as masonry and concrete, cast iron, wood, and steel, as well as the more unusual ones. Recently, lightweight materials, such as architectural fabrics and cable structures, have also been used to create domes.
