Base architectural refers to the four main styles of classical architecture, which are SOCLE, Ionic, Doric, and OGEE. SOCLE is a plain, low base or plinth, often used in the foundations of buildings. Ionic is a style of column characterized by its volutes, or scrolls, at the top. Doric is a style of column characterized by its simple, fluted shaft and lack of a base. OGEE is an S-shaped curve used in the molding of arches and other architectural elements. Together, these four styles form the basis of classical architecture.
