Historic England has awarded a grant of £31,020 to the Forest of Dean Building Preservation Trust to help repair Gunns Mill furnace in Mitcheldean. Gunns Mill is considered to be the best-preserved charcoal blast furnace in Britain.
The current furnace structure dates from the mid-17th century when the Forest of Dean was one of the most important centres for iron production in the country. It was converted to a papermill in 1743 but had fallen out of use by the 20th century.
The Forest of Dean Buildings Preservation Trust took on the ownership of Gunns Mill in 2013 and since then has undertaken a number of repairs to the structure with support from Historic England. This most recent round of funding will enable architects and engineers to design a structural solution to repair the timber frame of the roof of the bridge house and provide a usable space within.
The surviving lower tier of the building is a blast furnace built in 1625 on the site of earlier fulling and corn mills. That furnace was destroyed in the Civil War and was rebuilt by 1682, evidenced by cast iron lintels with cast dates of 1682 and 1683. The charge house roof on the upper tier north side has been dendro-dated from this time. It continued as a blast furnace until 1738.
