The dome is the fifth-largest in the world and rises 307 feet above the ground.
The building was constructed using over 7,900 tons of structural steel.
The rotunda was the site of the 1978 assassination of Mayor George Moscone and Supervisor Harvey Milk.
The gold-leafing on the dome was reapplied in 1999 as part of a seismic retrofit and restoration project.
The interior lighting features custom-designed chandeliers originally intended for the Panama-Pacific International Exposition.
The structure is built on a base isolation system designed to withstand a magnitude 8.3 earthquake.
The site occupies two full city blocks between Van Ness Avenue and Polk Street.
San Francisco City Hall is an exemplar of the City Beautiful movement, reconstructed following the 1906 earthquake. The current structure, completed in 1915, features a dome that stands taller than the United States Capitol in Washington D.C. It is designed in the Beaux-Arts architectural style, characterized by massive columns, granite, and limestone masonry. The interior rotunda is defined by a grand staircase leading to the mayor's office and legislative chambers. It functions as the primary administrative headquarters for the City and County of San Francisco. The building is a historic landmark recognized for its elaborate ornamentation and structural engineering. It serves as a popular venue for civil and ceremonial functions, including weddings. The exterior is illuminated at night, highlighting its neoclassical detail.
