In a hidden underwater village called La Marmotta in Italy, well-preserved artifacts were discovered in 1989, including five canoes made from hollowed-out trees up to 32 feet long. Estimated to be 7,000 years old, these boats displayed advanced maritime technology. International researchers revisited the site, shedding light on the bustling Mediterranean trade suggested by the canoes. Made from different woods for varying weights and strengths, these vessels may have been equipped with sails, outriggers, and support floats. The discovery challenges previous views of Neolithic farming groups, showcasing a level of social organization not previously considered in the area at the time.
