We were driving up the coast near Dirleton and Longniddry when we saw these concrete blocks lining the beach. Since we (originally) didn’t have the foggiest idea what they were (tidebreaks?) we stopped and had to wander out to look. They are pretty big — that’s Mark standing on top of one — and line probably a mile of the coastline? They appear to be coastal defenses against German landings, preventing any landing craft from making it up the beach.
These are snails — hundreds upon hundreds of tiny little snails sticking to the rocks on the shore. You could barely walk without squishing a few, and they covered nearly every crevice and stone. I wouldn’t walk barefoot around here.
