Gwaith Haearn Sirhowy

In 1818 the works were acquired by James Harford of Harford, Partridge and Co. of Ebbw Vale and, from this date on, were operated as part of the Ebbw Vale Ironworks in the valley to the east. Sirhowy supplied Ebbw Vale with pig iron and there it was worked into wrought iron and, from the end of the 19th century onwards, into steel.
