The architectural firm of D.H. Burnham & Co. designed this building in classic Beaux Arts style.
The building complements its next-door neighbor, Union Station—also designed by Burnham & Co. Daniel Burnham, the company’s founder, developed the National Mall and many other prominent Washington sites.
The historic lobby formerly served as the main service area of the Washington City Post Office. The USPS renovated the lobby in 1989, restoring every foot of the space to its original grandeur.
