Pillbox 030, Turtle Cove [1939- ]
If you are looking from the beach out to sea, this pillbox is at the back of the beach on your left.
As you walk towards it you'll see it has a metal door in good condition (not the original). I guess it is used as a store room for the people working at the beach.
Looking at the front you'll see these two loopholes. Their metal doors are still intact, though the hinges seem frozen with rust.
