Description

The Hermitage is an octagonal Gothick folly dating from the early 19th century. It features a tall pyramidal slate roof, which was originally thatched according to an 1825 sketch, aligning with the building's rustic character. The corners are adorned with roughly hewn and halved tree trunks, believed to be Spanish walnut, creating the appearance of supporting the roof. Similar halved branches are found under the eaves, while the walls are constructed of coursed stone. At one time, a cross was placed at the apex of the roof when it was converted into a chapel.

Access is from the northern side through a pointed archway leading to a boarded door. The windows vary in design: two sides have large circular windows with quatrefoil cusping, one side features a small quatrefoil window, another has a two-light cusped window, and one displays a Maltese cross-shaped light, while two sides are blind. Inside, the walls are plastered and feature Gothick panels, giving the space a chapter-house-like character.

Local climate

Hermitage sits in one of the wettest parts of the UK, with an average of 1,370 mm of rain a year. This makes it wetter than 97% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 98% of listed buildings.

It experiences an average of 20 freeze-thaw cycles a year, fewer than 78% of listed buildings. Of these, 9 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
