Heritage Open Day: Drop in and celebrate Heritage Open Days at this Grade II listed Watermill. Marvel in the layers of architecture of Stretton Watermill dating back to 1351, in this fine example of timber-framing and over-cladding. A beautiful model can be de-constructed to show the development of the building. There aren’t many places which take you back in time while you enjoy a picnic by the pond, as the waterwheel turns. Let the miller delight and entertain the whole family on a tour, with tales of the past and demonstrations of the machinery.
