Coit Tower
Coit Tower
Historical landmark
14 mins
Coit Tower, a slender white concrete column rising from the top of Telegraph Hill, has been an emblem of San Francisco’s skyline since its completion in 1933, a welcoming beacon to visitors and residents alike. Its observation deck, reached by elevator (tickets can be purchased in the gift shop), provides 360-degree views of the city and bay, including the Golden Gate and Bay bridges. The simple fluted tower is named for Lillie Hitchcock Coit, a wealthy eccentric and patron of the city’s firefighters. Coit died in 1929, leaving a substantial bequest “for the purpose of adding to the beauty of the city I have always loved.” The funds were used to build both the tower and a monument to Coit’s beloved volunteer firefighters, in nearby Washington Square. The tower was designed by the firm of Arthur Brown, Jr., architect of San Francisco’s City Hall. Contrary to popular belief, Coit Tower was not designed to resemble a firehose nozzle.
