"Frosterley is on the A689 almost directly between Wolsingham and Stanhope and the village is famous for its marble quarries. Its name originally meant the forest lea. There are many old quarries in the area although all are now closed. The marble was famous throughout the county and beyond; at Brancepeth the font is an example of a polished block and there is another in Frosterley churcn which was only built in 1869."

A modern bridge to the east of Frosterley next to a ford it gives accesss to Durham Industrial Minerals Broadwood Quarry where mining and processing of fluorspar and by-products, including gravels takes place. It replaced an earlier narrower bridge nearby. A 19C bridge also once existed, and there is a ford nearby.
