The network of criss-cross lines is 620 miles off the coast of north west Africa near the Canary Islands on the floor of the Atlantic Ocean.

The perfect rectangle – which is around the size of Wales – was noticed on the search giant's underwater exploration tool by an aeronautical engineer who claims it looks like an "aerial map" of a city.

The underwater image can be found at the co-ordinates 31 15'15.53N 24 15'30.53W.
