Description

Yeolmbridge Mill is a water mill, likely dating from the early 19th century. It is constructed of stone rubble with a rag slate roof, featuring hipped ends and a lower slate roof with a gable to the rear wing. The original design included an overshot water wheel at the front, and an entrance through a smaller, later 19th-century wing at the rear.

The overall plan is rectangular. The ground rises towards the rear, resulting in the stone floor being partly below ground level. Remnants of a slate launder for the overshot wheel are visible. The rear two-storey extension features a canted corner on the right. Plank doors are present on the ground and first floors, with a dressed stone arch at the ground-floor entrance and a timber lintel above.

The interior is not accessible, but the three-storey height suggests that the stone and bin floors may remain intact, despite the removal of the original machinery.

Local climate

Yeolmbridge Mill sits in a wetter-than-average part of the UK, with an average of 1,040 mm of rain a year. This makes it wetter than 84% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 85% of listed buildings.

It experiences an average of 19 freeze-thaw cycles a year, fewer than 81% of listed buildings. Of these, 8 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.
