San Francisco's City Hall - Architectural Masterpiece


It is common to hear visitors say our San Francisco City Hall rivals the renowned Paris Opera House for opulence and majesty.

Opened in 1915 after a ground-up rebuilding after the Great 1906 Earthquake it is now designated as a National Landmark and is highly regarded as a true national treasure. City Hall was designed by architect Arthur Brown Jr., who also designed San Francisco's Memorial Opera House, Veterans Building, Temple Emanuel, Coit Tower and 50 United Nations Plaza.


In 1989 another massive rebuilding of City Hall began. This time the project was not to repair major earthquake damage, but to prevent it in the future. San Francisco City Hall is now one of the safest buildings in the world if you're caught in a major earthquake.


During an earthquake the massive dome acts as a pendulum. A base isolation system separates the building from the ground, thus interrupting the energy before it enters the structure and accelerates the dome. This is done with the installation of rubber and steel discs (base isolators) under each column. A four-foot moat around the building allows it to move side to side without being attached to the earth. San Francisco City Hall is now the largest base isolated building in the world and the only isolated national landmark. It has now been designed to remain operational even after a great earthquake.


Public tours of San Francisco City Hall are readily available to everyone. They are conducted Monday - Friday 10:00 am, 12:00 noon and 2:00 pm. All tours run 45 minutes to an hour.
