Allen Mill - Circa 1890

A postcard view of the Beaumont’s smelt mill at Allen Mill. Mainly constructed 1835-40, by 1847 it comprised two calcining furnaces, six roasting furnaces, nine ore-hearths, two reverberatory furnaces, one reducing furnace, four refining furnaces, one slag hearth and a separating house with 18 Pattinson pots.

Later the smelt mill was connected to the nearby Hexham and Allendale Railway. By the end of 1896, with falling output from the Allendale mines the mill was closed.
