In theatre and performing arts, the stage (sometimes referred to as the deck in stagecraft) is a designated space for the performance of productions. The stage serves as a space for actors or performers and a focal point (the screen in cinema theaters) for the audience. As an architectural feature, the stage may consist of a platform (often raised) or series of platforms. In some cases, these may be temporary or adjustable but in theaters and other buildings devoted to such productions, the stage is often a permanent feature.
There are several types of stages that vary as to the usage and the relation of the audience to them.
