It’s been fifteen months since I was last visited the Kilton Ironstone Mine and the reinforced concrete winder house seems to have deteriorated noticeably. Large pieces of concrete have fallen off exposing the mesh reinforcement. The building was built in the late 1930s to house the 370 brake horse power electric winder motor. At that time the mine was operated by Dorman, Long & Co. Ltd. In the distance is the conical spoil tip which is visible for miles around.
