Coombe Mill

Coombe Mill is a watermill dating from 1842, constructed of rubblestone with rubble quoins and a slate roof featuring gable ends and a small brick chimney on the right gable. The building is three storeys high with a part attic floor that was likely added later. It has a regular two-window front, with two small 2-light timber window frames on each floor, except for the bottom right, where there is a stable plank door. Each window has iron stanchions and some lapped glass, with slate sills under thin timber lintels. There is a small opening with a stone surround adjacent to the left quoin. The right gable end wall has four similar windows symmetrically placed, while the left gable end wall has two windows above an iron overshot water wheel that is fed from a timber launder with timber paddles. A low dwarf wall in front of the waterwheel was introduced after 1967. A plank door leads to the second floor at the rear.

Inside, much of the machinery and gearing is intact and well-preserved. The ground floor features a cog pit raised on a stone platform, with a pit wheel that has timber side-on cogs engaging an iron waller that revolves a vertical iron shaft. The first floor contains a pair of French Buhr stones and a pair of Cornish granite stones in hursts, topped by grain hoppers. The dressing and bolting machines on the second floor were in working order as of 1972. The interior also includes three king post trusses, ladder stairs to each floor, and hinged trap doors in the centre of the floors. The ground floor is laid with slate.

Coombe Mill is likely situated on the site of the Stowe Manorial Mill and was in commercial use during the 1940s. It is referred to as "Stow Mill" in Charles Kingsley's novel Westward Ho! from 1855, where a character named Rose Salterne is imprisoned by her father.
