Fog Sutro Tower in San Francisco, CA
Sutro Tower is a 977 ft (298 m) three-pronged TV and radio antenna tower in San Francisco, California. Rising from a hill between Twin Peaks and Mount Sutro near Clarendon Heights, it is a prominent feature of the city skyline and a landmark for city residents and visitors. The tower was the tallest structure in San Francisco from the time of its completion until 2017, when it was surpassed by the Salesforce Tower.
Named after the family of Adolph Sutro, a businessman and former mayor of San Francisco whose grandson, Adolph Gilbert Sutro, built a mansion, La Avanzada, on their property in the highest peaks of San Francisco. In 1948, the mansion and property was sold to the American Broadcasting Company, where it became the original home of their San Francisco operation as KGO Television. The tower stands 297.8 m (977 ft) above ground and 552 m (1,811 ft) above sea level. It is the second tallest structure in the city by ground-to-tip height, though its mountain location overlooks the city’s downtown skyscrapers.
