Citando:
""Possibly these rocks were transported there by glaciers."

The 26ft tall object was discovered by Swedish explorer Peter Lindberg and his Ocean X team of marine explorers during a dive searching for a shipwreck. 

Despite the findings from Mr Brüchert, Ocean X maintain that it is not a natural structure.

Stefan Hogerborn, part of the Ocean X team, said their electrical equipment stopped working when they got to within 200 metres of the anomaly on the Baltic seabed."
