The earliest were water-powered corn mills, but later, after the opening of the new turnpike road between Tideswell and Buxton in 1812 which provided easier access, there were mills for timber, silk, cotton – and even distilled peppermint! Thus Miller’s Dale gets its name from the abundance of water-mills that once flourished here, and there was probably a mill here at the time of the Norman Conquest, although Miller’s Dale is not recorded in the Domesday Book. The earliest mention of a mill in the Wye Valley comes from the late thirteenth century Tideswell parish register which records the grant to a Tideswell miller of land to erect a corn mill. This mill was later owned by the monks of Lenton Abbey who farmed in nearby Monks Dale, and following the Dissolution, the ownership was transferred to the Duke of Devonshire.

Access was easy and yet inside is in decent condition, I think someone might be squatting inside but it's a different class of squatter as they like Rose wine and pot plants o_O Not really my thing but if your in the area and you like derps you've got a week until it's up for auction.
