Andrew W. Mellon Auditorium

The Andrew W. Mellon Auditorium features six Doric columns at its entrance, with marble and limestone walls rising seven stories into the Washington skyline.

President Franklin D. Roosevelt dedicated this neoclassical building in 1935, and it later hosted the signing of the North Atlantic Treaty establishing NATO in 1949.

The pediment above the entrance displays a sculpture titled Columbia, depicting the United States personified as a female figure with an eagle and youth.

This 750-seat venue connects two wings of the William Jefferson Clinton Federal Building and remains available for public events through Event Emissary management.

The limestone structure serves as the architectural centerpiece of Federal Triangle, providing the design motif for the adjacent government buildings.
