Heritage Open Day: See inside a fully working Victorian watermill. See the mighty waterwheel turn the cogs and stones to produce freshly milled grain. Branscombe's Manor Mill is a fully-functioning Victorian watermill, using the power of the village spring water to turn the machinery and produce flour. The waterwheel, weighing over three tons, and the cogs and stones inside the building are an impressive sight, and the noises and smells of yesteryear bring the building's industrious past to life.
