Statue erected by Abbot Bernard de Mun, because it was then located on his land. It was placed here because it dominates the place, at the top of the hill. It is now located in the dominial forest, the land having been bought by the State in 1971. The choice of a name 'Black Virgin' remains a mystery to this day.

This place is magical, from these chestnut trees over 300 years old, and from history, since this genius of the spirit that is Jean Jacques Rousseau, came there to write these manifestos.
