A mysterious Stonehenge-style monolith has been discovered in deep sea off the coast of Sicily - offering an insight into ancient civilisations lost beneath the waves.
The monolith, found by researchers from Tel Aviv University, has three holes of similar diameter along its length.
The researchers believe it was man-made around 10,000 years ago.
‘There are no reasonable known natural processes that may produce these elements,’ wrote Zvi Ben-Avraham of Tel Aviv University.
The monolith was found in 131 feet of water at Pantelleria Vecchia Bank - an area believed to have been colonised by an ancient civilisation which was submerged 9,500 years ago.
Some interpretations of Plato’s stories of ‘Atlantis’ identify the legendary ‘lost’ island with Sicily.
The researchers write, ‘The Sicilian Channel is one of the shallow shelves of the central Mediterranean region where the consequences of changing sea-level were most dramatic and intense.
‘This discovery reveals the technological innovation and development achieved by the Mesolithic inhabitants in the Sicilian Channel region.
‘Such an effort undoubtedly reveals important technical skills and great engineering. It could have been some sort of a lighthouse or an anchoring system, for example.’
