Description
An 18th-century water mill, situated within the parish of St Keverne. The mill is constructed of whitewashed rubble walls with a half-hipped slate roof and a rectangular plan. It has an asymmetrical two-window front, with two storeys. A partly intact 2-light casement window is present on the ground floor to the left, with an entrance to the right of centre. Two 2-light casement windows with glazing bars are located on the first floor. A rubble stone lean-to extends from the left-hand gable end. The ground rises to the right, facilitating loading, and steps lead up to the first-floor entrance within the right-hand gable end. The mill machinery is located low down near the ground floor, within a shallow cog pit. The water wheel, axle, and most of the ironwork are missing, but some wooden gears and two pairs of grinding stones remain. The mill is currently derelict. The site’s history dates back to 1258 and was originally part of the Traboe estate, which extended into the neighbouring parish of St Martin. The estate was granted to the monks of St Michael’s Mount by Robert, Earl of Mortain, around 1087. The mill, formerly known as Melyn Myhall, meaning St Michael's Mill, retains some original features.
