Gilder Lehrman Hall, named in honor of Richard Gilder and Lewis E. Lehrman, is the Morgan's first performance hall and a significant new concert venue for New York. The hall, located below ground in the northeast corner of the site, was designed by Renzo Piano and acousticians Eckhard Kahle and David Harvey, and features fine cherrywood paneling on the walls and ceiling and a flexible stage that allows for the accommodation of up to 260 people.
