Battery Townsley was top secret in WWII, and was a casemated battery with two 16" caliber guns (aka battleship guns) that shot one ton armor-piercing shells 25 miles out to sea. Kaboom!

Battery Townsley is just north of the Golden Gate, and stands guard over the entrance to the San Francisco Bay. Here we are looking south down the coast, with Rodeo Beach and Fort Cronkhite in the foreground.
Battery Townsley - 1938
The battery was constructed in 1938. It took almost two years, until the summer of 1940, to get the big guns and complex ready to fire rounds of live ammunition.
The battery had two main tunnels and a labyrinth of interconnected side bunkers.
These anchors were used to pull the big guns through the tunnels (the guns had to be replaced on a regular basis).
The metalwork in the battery complex is in a state of beautiful decay.
The artillery shells for the 16-inch caliber guns were huge.
