Los Angeles City Hall
Summary
Los Angeles City Hall, completed in 1928, is the center of the government of the city of Los Angeles, California, and houses the mayor's office and the meeting chambers and offices of the Los Angeles City Council. It is located in the Civic Center district of downtown Los Angeles in the city block bounded by Main, Temple, First, and Spring streets, which was the heart of the city's central business district during the 1880s and 1890s.
The Observation Deck or Tom Bradley Tower located on the 27th floor is open to the public. Access to City Hall is located off of Main St. The rotunda is located on the 3rd floor accessible by all elevators. To access the Tom Bradley Tower requires the “Express Car Only” for floors 1, 3, and 10 through 22 elevators. Once on the 22nd floor transition to the Gold 22 thru 26 elevator bank. Finally once on the 26th floor, access to the 27th can be reached by stairs or one more elevator. Public restrooms are located on the 3rd and 26th floor.
The building was designed by John Parkinson, John C. Austin, and Albert C. Martin, Sr., and was completed in 1928. Dedication ceremonies were held on April 26, 1928. It has 32 floors and, at high, is the tallest base-isolated structure in the world, having undergone a seismic retrofit from 1998 to 2001, so that the building will sustain minimal damage and remain functional after a magnitude 8.2 earthquake. The concrete in its tower was made with sand from each of California's 58 counties and water from its 21 historical missions. City Hall's distinctive tower was based on the shape of the Mausoleum of Mausolus, and shows the influence of the Los Angeles Public Library, completed shortly before the structure was begun. An image of City Hall has been on Los Angeles Police Department badges since 1940.
To keep the city's architecture harmonious, prior to the late 1950s the Charter of the City of Los Angeles did not permit any portion of any building other than a purely decorative tower to be more than .
