Grade II listed WW2 anti-tank obstacles constructed c1940 to protect the area in anticipation of the German invasion.

There are 3 types of obstacle to form the defensive line: cubes, pimples (a flat-topped pyramid often referred to as 'dragon's teeth') and caltrops.

Caltrops are a rare type of asymmetric concrete obstacle which are piled against the seawall. They reminded us of a bad game of Tetras. There are many kinds of anti-tank obstacles across the world, but the ones on the Isle of Grain are of special interest because of the different and unusual forms of obstacle which together, at nearly 600m in length, form an spectacular defence.

I have a habit of looking at bricks to see what is inscribed on them and there were loads scattered about on the beach!

Hope you enjoy.....
