Second World War anti-tank sea defences designed to repel a Nazi invasion were temporarily transformed into a giant artwork showing people rock climbing.
Beach artist Claire Eason spent four hours painstakingly carving the 100ft-long creation using a garden rake before her efforts were washed away by the tide.
She created the eye-catching artwork after stumbling across anti-tank defences which were placed on Beadnell Bay, in Northumberland, more than 75 years ago.
The giant concrete blocks were installed to halt a German invasion during the Second World War and remain visible today.
