In reviewing Iranian architecture, one realizes that the basic geometrical form is a square that is transferred to a dome, to create a tangible expression of mathematics and architectural beauty. In achieving a dome from a square, the architect creates not only the geometrical forms such as triangle, hexagon, and other polygonal shapes, but also provides an architectural environment in which these shapes blend with each other. Examples of which are visible in mosques, schools, public baths and other public buildings. The dome of Ganjali Khan Bath is a successful presentation of transferring a square to a beautiful dome, without the use of a belt or other metal elements to absorb the pressure.
