Description

The Stones Museum is a two-storey building featuring a three-window range constructed from rubble stone, with quoins, and topped with a red tile roof that has a stone stack at the west end. At the west end, there is a lean-to porch that includes late 20th-century glazed panels and a door. The south face of the building has round-headed windows with voussoir heads and stone sills. These are fitted with iron multi-pane windows that have radial glazing beneath arches. On the east end, there is a three-light metal-framed window with quarries, which is topped with a square hoodmould and has a stone sill. The north side has two similar windows and two large rooflights.

Inside the porch, there are two doors; the one on the right is original and features a large stone lintel. The interior consists of a single room that has been converted into a museum and includes a steel-framed gallery.

Stones Museum sits in one of the wettest parts of the UK, with an average of 1,220 mm of rain a year. This makes it wetter than 92% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 95% of listed buildings.

It experiences an average of 23 freeze-thaw cycles a year, fewer than 76% 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.
