Is this the world's smallest Neolithic ceremonial stone circle: Sadly not, these angular rocks were set into the top of a WW2 concrete anti-tank block. Most of the block is currently buried in the sand. Their purpose was to tear off the tracks of any Nazi tank that attempted to climb over them. Thankfully they were never put to the test.
The blocks, which stretch for 12 miles along the beach from Newburgh to Aberdeen, were hastily built by British and Polish soldiers in 1940 when invasion threatened. As you can see from the extra this block was signed by Frank, one of the soldiers involved.
