This is the amazing image which could show the fabled sunken city of Atlantis.
It shows a perfect rectangle the size of Wales lying on the bed of the Atlantic Ocean nearly 3½ miles down. A host of criss-crossing lines, looking like a map of a vast metropolis, are enclosed by the boundary.
They seem too vast and organised to be caused naturally. And last night the possibility of an extraordinary discovery had oceanographers and geophysicists captivated.
The site lies 620 miles off the west coast of Africa near the Canary Islands — a location for Atlantis seemingly suggested by the ancient philosopher Plato.
