Er Lannic cromlech, Neolithic cromlech in Arzon, France
The Er Lannic site contains two horseshoe-shaped stone circles arranged on a gentle slope, with the southern circle now submerged in water.
Archaeological excavations between 1923 and 1926 uncovered numerous artifacts including stone tools, pottery fragments, and evidence of ancient dwellings dating to 4000 BCE.
The standing stones feature engravings of axes and cup marks, revealing the artistic expressions and technical capabilities of Neolithic communities in Brittany.
Visitors can observe the stone circles from boats departing from Arzon, with guided tours offered in conjunction with visits to the Gavrinis cairn.
Rising sea levels over millennia transformed this originally inland megalithic monument into a partially submerged archaeological site in the Gulf of Morbihan.
