These 15 Abandoned Military Bases Will Leave You Speechless
15. Devil’s Slide Bunker
This haunting military bunker located in San Mateo County was built by the United States during World War II as the first point of defense for the harbor of San Francisco. During that time there was fear of the Japanese attacking by sea, unexpectedly. Military personnel would keep an eye on the shoreline with binoculars and sets of coordinates, looking for any signs of a potential attack. The structure was sold to a private owner in the 1980s and has become a popular photo opportunity for tourists visiting the area.
