Its an multiple quarry. I put them all under the same name,because they all minced in 1930/1940, for flint.The flint was used in the houses.The limestone was crushed and used on the farm field for fertilization.The limestone was of lesser quality and not weather resistant.Now a part of the quarry is used as a mushroom farm.The quarry is below a nature reserve,otherwise she will disappear in the cement mills for sure.
