The Harehope Quarry Project offers environmental education, field studies, rural skills training, community development, and community arts based from a limestone quarry in the North Pennines.
Limestone has been quarried at Harehope for more than 900 years.
Quarrying on a small-scale has taken place here since the 12th century. However, larger scale quarrying did not begin until 1901 and had stopped by 1931.
The quarry re-opened again in 1954 and continued until 1987. The quarry was used more recently as a tarmac coating plant with limestone being brought in from other quarries in Weardale.
Limestone from Harehope Quarry was used in the process of refining iron from iron ore. This process took place at ironworks in Consett, Tyneside and Teesside.
More recently the limestone has been used in the construction of roads.
The Frosterley Marble found within the limestone was quarried for its ornamental value and can been seen in the Chapel of the Nine Altars in Durham Cathedral as well at churches in Weardale and further afield.
