Why take advantage?
During the Neolithic period (5000 to 2000 BC), man became a farmer and shepherd, and built megalithic monuments, dolmens and menhirs, to honor his dead and his gods.
Menhirs (from the Breton Men, stone, and hir, long) are stones set vertically in the ground. Varying in size, they can be found singly or combined in alignments and cromlec'h (circles).
The Men-Ozac'h menhir, flooded at every tide, is an exceptional reminder of the rise in sea level since the Neolithic, a natural phenomenon exemplified by the covered walkways of Lerret in Kerlouan and Kernig in Plouescat.
Located in the commune of Plouguerneau, it is also known as the Saint-Cava menhir, and is called "la bonne soeur" (the good sister) by some of Lilia's inhabitants, no doubt due to its dark coating of seaweed.
