Le Diamant Theatre's main auditorium has seating for up to 625 people. The theater holds several practice rooms, offices, and a café, as well as a smaller hall with seating for around 150 people. In addition, with the use of cutting-edge technology, such as sophisticated lighting and sound systems, a retractable orchestra pit, and a hydraulic stage, the building is created to host complex performances. Diamant Theatre's facade is covered by a large glass volume that glistens in the sunlight. The glass panels were designed to resemble diamond facets, hence the name "Le Diamant." A significant cultural icon in Quebec City, the theater has grown to become one of the main tourist destinations.
