Sutro Tower is a 297.8 m (977 ft) three-pronged antenna tower near Clarendon Heights in San Francisco, California. Rising from a hill between Twin Peaks and Mount Sutro, it is a prominent part of the city skyline and a landmark for city residents and visitors. However, many local people opposed the tower even before it was completed, including criticism of the aesthetic effect the tower would have on the rest of San Francisco. San Francisco writer Herb Caen once wrote, “I keep waiting for it to stalk down the hill and attack the Golden Gate Bridge." Acknowledging both displeasure and affection for its undeniable prominence on the city's skyline, it is sometimes referred to light-heartedly as the Sutro Monster.
