Hartsop is a small village in the English Lake District. It lies in the Patterdale valley, near Brothers Water, Hayeswater and Kirkstone Pass. It consists of 17th-century grey stone cottages, like so many of its neighbours. Hartsop retains its historic image, in that, in common with a number of other small Cumbrian villages, it had houses with spinning galleries. It was also a lead mining community. A mile from the village is the small and remote lake of Hayeswater which serves as a reservoir for the town of Penrith about 12 miles away. Hartsop is part of the civil parish of Patterdale.
