Military power at the Golden Gate

For the first three-quarters of the 20th century, the Marin Headlands were fortified with weapons that evolved from cannon to nuclear warheads. The guns became more and more powerful, able to hit warships miles out to sea. Antiaircraft guns appeared on key hilltops during World War II, after the development of airplanes and aircraft carriers made aerial attack a possibility. Finally, during the Cold War, radar-guided Nike missiles bearing nuclear warheads were installed and remained ready for launch against enemy bombers until 1974.
The cement structures visible on the slope in front of you, one of Battery Wallace's two gun emplacements, started out as two open-air platforms built in 1919. In 1943, the concrete and earth casemate was constructed to protect the battery's artillery crew and two 12-inch cannon - with a range of nearly 17 miles.
