The Merriam-Webster dictionary defines “megalith” as: “a very large usually rough stone used in prehistoric cultures as a monument or building block”. While these stones are fairly large I’m not sure that I would call them “very” large (i.e.in the sense that the stones used at Stonehenge are “very” large). Somehow the word “minilith” comes to mind! At this site there are three largish standing stones (menhirs) and a large boulder carved with four female figures. The latter is a copy of the original (see below):

According to the town’s website (translated from the original French):

It is probable that the neolithic inhabitants of the region lodged in the Salève caves and pruned menhirs. One of these sacred stones was found at the beginning of the 19th century at the top of a mound at the place called Pierre-Grand. On one side are four sculptured female figures, probably dating from the Gallo-Roman period (120 BC to 400 AD), and which are at the origin of her name : The Pierre-aux-Dames. This megalith was classified as a historic monument in 1921 and has been preserved since 1942 at the Museum of Art and History of Geneva. In 1998, the municipality commissioned a large copy of it which can be admired today on the Town Hall Square.

The three small megaliths can be seen on the left.

A fascinating and unexpected find.
