Shepherd Wheel, one of the Sheffield Industrial Museums Trust trilogy, lies in the Porter Brook Valley, where the sylvan waterside splendour of the area adds to its charm. The water-driven grinding workshop on the site shows the visitor how those well-known Sheffield knives got so sharp, all the way back to the fifteenth century up to the 1930s. You will be well satisfied by a visit to these magnificently restored works, the only complete and working water-powered grinding works still in existence, housed in Grade II listed buildings, while the site is an official Scheduled Ancient Monument. A visit to the Shepherd Wheel includes hearing stories of times long gone and a walk along the dam fed by the River Porter in the footsteps of people who had done so for centuries. The Shepherd Wheel is open year-round, but check before you go, and general admission free of charge!
