Grove Mill

Grove Mill, formerly known as Lumhole Mill, has late 18th century origins but underwent significant rebuilding around 1830 for Shallcross and Sheldon Ltd., with additional extensions added in the late 19th century. The building is constructed from coursed, square, buff sandstone rubble and features a Kerridge stone-slate roof with a stone ridge and two stone chimneys. The original mill has a three-storey, nine-bay north front, with nine-pane fixed iron windows that have plain lintels and sills. A vehicle entrance was inserted under a steel lintel around 1980.

To the left, there is a one-bay beam engine house and a lean-to boilerhouse that contains a Cornish boiler. To the right, two bays were added, which include a single-storey building that once housed a hand-fired gas retort, with the chimney located in the corner. The south front features a projecting staircase tower beneath a gabled roof, along with loading bays and a setting for a clock. A steel channel directs water from the pool to the waterwheel.

Inside, the ground and first floors have suffered fire damage. At the east end, there is a 26-foot diameter all-iron overshot waterwheel, which is paired with a double-action condensing beam engine made by Sherratts of Salford, added around 1840. Much of the gearing and drive system remains intact, and there is a spiral stone staircase in the tower. Grove Mill is considered the last example of a mill where water-powered and steam machinery were used together and have survived intact.
