Description

This is a simple milestone made of a squared slab of stone with an angled top. It has been whitewashed and features incised lettering that reads "Mach / 2 M." Below the lettering, there is a benchmark.

Local climate

Milestone sits in one of the wettest parts of the UK, with an average of 1,320 mm of rain a year. This makes it wetter than 95% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 93% of listed buildings.

It experiences an average of 31 freeze-thaw cycles a year, fewer than 62% of listed buildings. Of these, 15 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.
