Pantelleria Vecchia Bank Megalith

The Pantelleria Vecchia Bank Megalith is a 12-metre-long, 15-ton monolith of calcirudite limestone discovered at 40 metres depth in the Sicilian Channel between Sicily and Tunisia. Broken into two parts, it features three deliberately drilled holes of consistent diameter with no known natural process to explain them, providing strong evidence of human craftsmanship. Radiocarbon dating of embedded shell fragments confirms the stone is at least 9,350 years old, placing it in the early Mesolithic period when the Pantelleria Vecchia Bank was still an island above sea level.
