Understage

Understage refers to the area beneath the main performance surface of a stage. This space can serve various practical and artistic functions in theatrical and other live performance venues. In many traditional proscenium theaters, the understage often contains mechanical systems that allow for the movement of stage elements. These can include trap doors, which provide a means for actors or scenery to appear or disappear from the stage, and elevator systems that can raise or lower sections of the stage floor or entire set pieces. The understage also typically houses equipment such as lighting dimmers, rigging systems, and other technical machinery necessary for a production.

Beyond its functional role, the understage can also be utilized for storage of props, set construction, and as a backstage area for performers. In some more modern designs, the understage might be a deeper, more elaborate space capable of housing complex automated scenery or creating distinct levels within the performance area itself. The accessibility and configuration of the understage are significant considerations during the design and construction of a performance venue, impacting both the technical capabilities and the creative possibilities of the space. Access to the understage is usually restricted to technical crew and performers during a show for safety and operational reasons.
