Archaeologists excavating an industrial estate… found a megalithic complex.
Neolithic seafaring
Discovered as recently as 1989, the Neolithic settlement submerged beneath the waters of Lake Bracciano, at La Marmotta, near Rome, Italy, has yielded rich evidence of life 7,000 years ago. New analysis of the five boats found at the site suggest that they could have been used for the sea voyages that led to the spread of Neolithic practices to the islands of the Mediterranean.
A paper in the journal PLOS One (https://doi.org/10.1371/journal.pone.0299765) says that earlier boats dating back 10,000 years have been found in European waterways, but all were designed for use on rivers and lakes. The five hollowed-out tree trunks excavated from La Marmotta are substantially larger than earlier boats and one has four transverse ribs designed to provide additional strength and improve its handling.
