Moira Furnace was an Ironworks Factory with a huge blast furnace, built in the reign of King George III. Located by the Ashby-de-la-Zouch canal in Moira, Derbyshire. In 1804, the Earl of Moira ordered for the construction of the furnace to take advantage of the amount of iron ore and coal that was present underground in the surrounding Ashby Woulds owned by him. However, it was during this period that the development in blast furnace design was ongoing, and so some of its features at Moira Furnace appeared to have been unsuccessful. In 1806, it was first opened and the blasting began. It would only last until 1811, not because iron became less valuable, but because it had experienced continual problems. Recorded documents state that bad design, bad construction, bad management and even bad raw materials led to the closure of the furnace, just 5 years after it first opened. The furnace was then left abandoned, with iron ore left inside, partially smelted.
