Skaggs Island was a Top Secret radio surveillance and cryptologic communications installation operated by the Navy. Opened in 1941, it was hidden in plain sight, between Sonoma and San Francisco Bay. Several antennas, miles across, were built in the surrounding marshlands. They were used to intercept secret radio communications from all around the globe and the cryptologists stationed there would then decode them. The base contained over 100 buildings including dozens of houses, a mess hall, recreation center, bachelor’s quarters, and administrative buildings.
In 1993 Skaggs Island was decommissioned and simply abandoned. Over the years security was hit and miss at best. In 2005 and ’06 the gate was frequently left open and I was able to just drive right onto the base several times. I frequently had to dodge late night vandals and copper thieves who were methodically destroying the site, building by building.
In 2011 the entire base was razed and turned back into marshlands. All the structures you see in this set are gone.
