In architecture, a plinth is the base or platform upon which a column, pedestal, statue, monument or structure rests. Gottfried Semper's The Four Elements of Architecture (1851) posited that the plinth, the hearth, the roof, and the wall make up all of architectural theory. The plinth usually rests directly on the ground, or "stylobate". According to Semper, the plinth exists to negotiate between a structure and the ground. Semper's theory has been influential in the development of architecture.
Many houses in flood-prone rural areas of Bangladesh are built on plinths ("homestead plinths").
The word is also used for the base of a cabinet or an audio turntable.
