A portico is a classical porch with a decorated entablature supported on columns, and often completed by a triangular pediment. On modern buildings in classical style, the pediment sometimes contains a clock dial. The term 'portico clock' is also applied to the style of French clock usually known by the name 'Empire'. Here the entablature is supported by four columns on a base, and the movement is suspended below it with the pendulum exposed. This design can also be seen in earlier examples from Austria, the essential feature being the entablature supported by columns. Other Austrian designs, especially in the Biedermeier period, include columns, but do not necessarily qualify as portico clocks.
