Blackwell Mill is a location in Derbyshire, near to the village of Blackwell near Buxton, but not part of it. There was once a corn mill on the River Wye which may have dated from 1066. Most of it has disappeared, apart from the weir. What is left is marked as an Ancient Monument. It stands at the meeting point of several valleys: Great Rocks Dale, Chee Dale and Ashford Dale. In times past the Manchester Turnpike forded the river. It marks the northern end of the public path from Bakewell, used by walkers and cyclists, called the Monsal Trail.
