my love for concrete structures continues

 .

Located just east of the Cape May Point Light House in what is now Cape May Point State Park, the bunker was built by the US Army Corps of Engineers during the early months of the Second World War. It contained heavy artillery and was manned by a rotating detail of naval gunnery crews, who spent hours on end scanning the horizon for enemy surface ships and submarines. (In fact, a German U-Boat commander surrendered his vessel just off the coast of Cape May at the end of World War Two) This bunker was part of a coastal defense system during World War II. In front of this bunker were 6" turrets and 155MM guns. The bunker was originally 900 feet inland. Coastal erosion had taken it's toll on the beach.

This bunker is located above the pacific ocean at a part of the coast called "devil's slide" few miles south of San Francisco. I want to thanks Kevin L. for sending me this tip, this is truly an amazing location. I had the chance to go there and take some pictures, I can tell that the name "devil's slide" is perfectly appropriate!

There are 2 sets of bunkers in pretty much the same location, the lone bunker to the south, built originally on a thick pillar of sandstone. The stone has eroded so much that the building hangs over it on all sides. And some more to the north.

The following description from the United States Army Corps of Engineers website refers to those constructions (the one to the north) : "Prior to 01 July 1940, the War Department acquired 9.61 ... acres for a triangulation station and observation site. Devil's Slide was one of a series of observation posts during pre-radar days and was a part of the Harbor Defense of San Francisco. Military personnel would use binoculars and compasses to search for ships at sea and relay the position ... using information received from other observation posts. Improvements to the site began in 1943, and included three observation pill-boxes, one electric generator bunker, one communications and command bunker, and an observation tower."
