A Medieval Blast Furnace - The Old Furnace, Oakamoor, Staffordshire

The team are revisiting the garden of Furnace Cottage in Churnet Valley, where the previous excavation of an Elizabethan blast furnace produced evidence of much earlier iron-making. Stewart surveys the landscape, to piece together a picture of water flow and other features essential to iron smelting. But John is convinced that there is strong geophysical evidence for a furnace a mile away at Eastwall Farm. It could even be water-powered - a major discovery. They build a medieval style bloomery. They are joined by historian Pete Brown, and archaeologists David Cranstone, Bill Klemperer, Deb Ford, Gerry McDonnell, Tim Young.
