Home to many of the Metropolitan Museum's Concert & Lectures series, Grace Rainey Rogers Auditorium was added to the Musuem at a cost of $9.6 million in the 1950s. The 708-seat auditorium was designed by Voorhees, Walker, Foley & Smith while the acoustics were designed by Bolt, Beranek & Newman of Cambridge, Mass. The auditorium's 1,450-square-foot stage can accommodate a full symphony orchestra with chorus and yet is intimate enough to host a single speaker.
