Bersham Ironworks, in the village of Bersham just outside Wrexham, was one of the most important foundries of the Industrial Revolution. John Wilkinson established his cannon-boring operation here in 1763, and it was at Bersham that he developed the precision boring techniques that transformed steam engine manufacture. The foundry also produced iron pipes, cylinders, and structural components for bridges across Britain and the new industrial world.
The site today is partly preserved as a heritage attraction, with surviving remains of the foundry buildings and an interpretation centre covering Wilkinson's significance and the broader story of north Wales's iron industry. The surrounding Clywedog Valley heritage trail connects Bersham with other industrial sites in the area, including Minera Lead Mines (worked from Roman times until the 20th century) to the west. A visit here adds the industrial dimension to Wrexham that the church and country house don't cover.
