Mill Pond Lade and Sluices at Mill of Benholm

The Mill of Benholm is an 18th-century meal mill, significantly altered and rebuilt in 1817 and later, with a kiln likely added in the early 19th century. It was restored and the water wheel renewed between 1987 and 1995. This represents a rare survival of a small, two-storey, L-plan, water-powered mill with a piend roof, retaining its working order. The complex is situated on a sheltered site alongside the Burn of Benholm, below weirs at the confluence with the Castle Burn to the northwest. The site also incorporates a mill dam and lade, a former miller’s house (now a café), a former byre (now toilets), a barn (now a workshop), and an old grain store (now a miller’s office), all converted but maintaining a traditional appearance.

The mill itself is constructed of snecked rubble with roughly squared dressings, some timber lintels, and brick infill. The north-facing entrance elevation is single-storey, featuring a door that breaks the eaves under a catslide roof, a small window abutting the eaves, and evidence of a kiln extension. The south-facing elevation, overlooking the burn, displays distinctive kiln stonework, a door bearing the carved lintel “William Davidson 1817”, and a projecting bay to the far right. An overshot water wheel is located to the east.

The mill pond, lade, and sluices consist of a dual sluice system at the confluence of the Castle Burn and Burn of Benholm, diverting water to the mill lade and dam. A further sluice at the east end of the dam flows under a roadway to a trowse (lade).

The former miller’s house is a single-storey, three-bay, rectangular-plan range with an asymmetrical eastern entrance elevation and a symmetrical western elevation. The former byre, now used as toilets, is a small single-storey, three-bay, rectangular-plan range, facing the burn and forming an L-plan alongside a lean-to attached to the northeast angle of the café. The old grain store is a small, single-storey, three-bay, rectangular-plan range with a piend roof, located to the northeast.

Small-pane glazing is featured in fixed and casement timber windows throughout, and the roof is covered with grey slates. The interior demonstrates a remarkable survival of original workings, including an upper floor with two pairs of anti-clockwise rotating millstones (47 inches in diameter, segmented French burr stones), and a lower floor with a fanner, shaker, meal sieve, and fanner. Other machinery includes a chain hoist, two bucket elevators, sieves, and sack hoists. The water wheel is a 12-foot diameter cast iron wheel with timber cogs, 32 timber buckets, and 8 timber spokes, with phosphor bronze axle bushes and a steel axle connecting the waterwheel to the pit wheel.
