Bonawe Iron Furnace is one of the region’s most unusual historical sights. Near Taynuilt (not Bonawe), and dating from 1753, it was built by an iron-smelting company from Cumbria because of the abundance of birch and oak in the area. The coppiced wood was made into the charcoal that was needed for smelting the iron. It's now a tranquil, beautiful place, with the old buildings picturesquely arranged around a green hillside, and there's great background information on the iron industry. Take a picnic!
