Grasslees Water Mill (site)

Map showing the Scheduled Monument area for the Grasslees watermill complex (ruins).

Grasslees Mill, located about ¼mile north-east of Grasslees farm, is a ruined watermill complex, dating from the 18th century or earlier. The complex included the mill, a corn drying kiln building and a walled enclosure. The mill race was fed from a small spring to the north and by a mill race from a large pond to the west.

The earliest documentary reference to a mill here is in 1618, when the 'Mill of Grisleays' was held by Alan and Thomas Wanlass.^[1] Whellan's 1855 directory lists William, John, and Andrew Stevenson as millers at Grasslees Mill^[2]. The mill appears to have been abandoned in the later 19th century. The remains visible today are earthworks of the buildings, with some stone walls still protruding through the turf. The wheel pit collapsed in 1994, but originally measured 1m wide by 6m long. The site is a Scheduled Monument on the National Heritage List for England. It was added to the  Heritage at Risk list in late 2023.
