Theatre buildings are specially designed structures where live performances, such as plays, musicals, and concerts, take place. They often feature a stage, seating for the audience, and various technical facilities for lighting and sound. The architecture of these buildings can vary widely, from historic Victorian theatres to modern black box venues, each offering a unique atmosphere for performances. Inside a theatre, the layout typically includes a proscenium arch that frames the stage, allowing the audience to focus on the action. Many theatres also have backstage areas for actors and crew, as well as dressing rooms and storage for props and costumes. The design and acoustics of a theatre are crucial for enhancing the overall experience of the performance.
