The Pantelleria Vecchia Bank Megalith is an anomalous artifact of uncertain origin, located on the Pantelleria Vecchia Bank in the Strait of Sicily between Sicily and Tunisia, at a depth of 40 meters underwater.
The megalith is a large block of sedimentary calcirudite limestone measuring 12 meters long, and weighing 15 tons.
[1] The stone may have been carved when the area last stood above ocean level around 10,000 years ago during the early Mesolithic.
[3] The megalith was discovered by Emanuele Lodolo and Zvi Ben-Avraham in 2015 during a seafloor mapping survey in an area called the Pantelleria Vecchia Bank, located about 60 kilometers south of Sicily.
[2] After scans indicated a large roughly rectangular object, divers and cameras were deployed to capture photographic evidence.
