Coastal erosion has recently revealed what I believe are the foundations of WW2 anti-tank cubes at Millclose Howle, they were not visible on the current Google Earth images.
The cubes would have blocked access at this point by invading tanks.
The cubes themselves were probably destroyed soon after the war, but these stubs remain.
A block of three is fully revealed, but there are more still hidden under the soil that appear more intact.
