With the erosion, the lime sediment rocks can sometimes take an original form.
From here, you can see a spectacular geological phenomenon called a limestone pot hole. The surface limestones are bare, permeable, chiselled and streaked by the corrosive effects of water. This phenomenon is revealed by the impression of fields of broken stones laid out before you. The cut up rock, sometimes very regular on its stratification bed, can be mistaken for archaeological relics.
Here, it is almost certain that the Gallo-Romans used a part of the limestones available on the surface of the ground, as raw material for the nearby lime kilns.
