The old P.C. Saxena Auditorium at IIT Bombay is a historically significant venue that has hosted numerous important events over the years. The old P.C. Saxena Auditorium has a traditional architecture typical of academic buildings from the middle of the 20th century. It blends a simple architectural style with utility. The auditorium is a big, one-story structure, including a large main hall. The building has a large stage, a seating section for the auditorium, and backstage and green rooms for support staff. The auditorium's strong and resilient construction, which reflects the architectural fads of the time, was achieved through the use of brick and concrete. To guarantee optimal visibility for every guest, the room is furnished with layers of seating. Its simple sound and lighting systems are appropriate for a variety of occasions. The auditorium has been named in honour of Professor P.C. Saxena, a pioneering figure in IIT Bombay's history. The auditorium commemorates his contributions to the institution.
