Heritage Open Day: Look inside a working Victorian watermill, from waterwheel to grinding stones. Experience the evocative atmosphere of a Victorian watermill. See the wheel rotate, the cogs turn and take in the the sounds and vibrations that a miller 150 years ago would have known as part of their day at work. Try on a miller's costume, have a go at grinding with a quern and see if you can spot the rats (don't worry - they're not real!).
