50 United Nations Plaza Federal Office Building (San Francisco)

Fifty United Nations Plaza stands as a monumental five-story block of granite, defined by a grand colonnade of two-story Doric columns along its south facade. Completed in nineteen thirty-six, the structure was designed by Arthur Brown, Junior, the architect behind the city’s landmark City Hall, to serve as the final piece of the ambitious San Francisco Civic Center complex. The building exemplifies Second Renaissance Revival architecture, a core element of the City Beautiful movement intended to project stability and classical order through its heavy masonry and formal, symmetrical proportions.
