Proscenium arch

A proscenium arch is a large, arch-shaped frame that creates a picture-like opening on a stage. It separates the stage from the audience and frames the performance, much like a window. This design directs the audience’s attention inward and enhances the visual experience by focusing on the actors and scenery within the stage area. Common in traditional theaters, the proscenium arch provides a clear boundary and can also support stage curtains and lighting equipment. Overall, it acts as a theatrical framing device that emphasizes the performance space and enhances the viewing experience.
