Description

Duddon Iron Furnace is a Grade II* listed iron furnace for charcoal smelting, built around 1737. The structure is made of stone rubble and has a square shape with extensions to the west that are built into the slope of the ground. It features deeply splayed furnace openings, with the eastern opening having iron lintels and the southern opening being round-arched. There is a smaller square structure on top that has a round-headed opening to the west, which is made with long thin voussoirs and includes a 20th-century inserted door, accessed by a 20th-century ramp. The rear extensions have half relieving arches and flat arched window openings, and a small wing to the south retains one gable. Footings of demolished structures are present to the south and east, along with a wheel pit to the north. This is the best surviving charcoal-fired furnace in the South Lakes district and is designated as a Scheduled Ancient Monument.

Local climate

Duddon Iron Furnace sits in one of the wettest parts of the UK, with an average of 1,610 mm of rain a year. This makes it wetter than 99% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 99% of listed buildings.

It experiences an average of 28 freeze-thaw cycles a year, fewer than 70% of listed buildings. Of these, 12 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.
