The Rennie mill is situation in Milladen, which is on the banks of the River Ugie, in the Aberdeenshire countryside, just 11 miles west of the most eastern point of Scotland. Just south of Aden Country Park, between Mintlaw and Old Deer, the Rennie mill has remained in the same spot since 1798, in an ideal rustic setting, with exclusive Salmon fishing rights and a waterwheel which once powered the carding sets many years ago, but has since been set up to generate electricity by natural hydro power from the river Ugie.
