History

The Union Ironworks was established in the area in 1800 - remains survive in the field to S. In 1803 the majority share was taken by the Crawshays of Cyfarthfa, Benjamin Hall and Watkin George, and the works was expanded c1804 by the opening of a new furnace in Rhymney. The works passed in 1810 to Benjamin Hall who carried out further improvements. In 1825 the Bute Ironworks was established across the river to S and in 1837 the sites were amalgamated to form the Rhymney Iron Company. Rhymney House was built c1801 as the Manager's residence on ground leased from the Duke of Beaufort. In 1834 it was the site of an attack by 'The Scotch Cattle', bands of disaffected workers disguised with horned head-dresses, blackened faces and draped in skins, protesting against working conditions and practices. Richard Johnson was manager at this time. 'Herds' came from Rhymney, Sirhowy, Tredegar and Dowlais but a public hanging in Blackwood in 1830 diverted activity into the Chartist movement. Plaque in church records Henry Trump (d 1895) of Rhymney House as manager of Rhymney Ironworks and was for many years home of Maddox family. Later became the Ffynnon Glas, Cristals, the Three Counties Club and currently the Rhymney House Hotel.
