Harboro Rocks, also known as Harborough Rocks, are located close to Hoben International factory near Brassington, Derbyshire.
The rocks are used for climbing and clay pigeons shooting. On top of the rocks a stone chair has been carved out of a standing stone, once a chambered Neolithic tomb, quite close to the trig point. It was also home to an Iron Age settlement.
A cave with a wide entrance is also located on Harboro Rocks. It has a natural chimney and a large rock in the centre of the cave. It was excavated in the early part of the 20th century. Pot shards, a bronze pin and brooch were found along side iron spearheads and part of a shale bracelet. All have been dated to the Iron Age. Today the cave is used as a shelter to climbers and walkers caught out in bad weather.
Below the rocks stands the remains of an old mill. It was used to process the silica sands and iron oxides quarried in the area. These were used in paints and refractory bricks.
