Delabole Slate Quarry
A Must See When Visiting Cornwall – Come and visit the oldest working slate quarry in England. One of the most important Industrial Heritage sites in Britain today.
Delabole Slate Quarry has been in operation for around 1000 years and over 10 million tonnes of slate has been quarried since it was first recorded in the Domesday Book of 1086. Records show the manor of Deliou under the ownership of William the Conqueror’s brother-in-law, Count de Mortaine, the 1st Earl of Cornwall. The Normans would have required the slate for their castle and estate building program across the south of England.
Join a tour and see world renowned Delabole roofing slate split by hand just as it has been for centuries. The quarry is now almost 500 feet deep and over 1.5 miles around. Once the largest man-made hole in Europe, it is an amazing sight to see. So if you come to Cornwall, be sure not to miss it.
