Battery Townsley

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!

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.

This is some old military graffiti artwork from the 50's or 60's. By then Nike missiles, not the big guns, guarded the coast.

Blast chamber

This tunnel/chamber was added in the 60's to test blast effects, long after the battery was decommissioned post WWII.

These spotting scopes were in hardened bunkers located at distances from Battery Townsley to allow for precise triangulation.

The exterior walls of the bunker were studded with steel and iron, which have left washes of rust.
