The 'Ironmaster' William Crawshay commissioned Cyfarthfa Castle in 1824. This grand castellated mansion overlooked his immensely successful ironworks and has been called, "the most impressive monument of the Industrial Iron Age in South Wales".

At the Museum, you can admire the extensive fine and decorative art collections, including Swansea, Nantgarw and Wedgwood porcelain. Stroll through the atmospheric social and industrial history galleries, which chart the rise of this once great ironmaking town; learn about Richard Trevithick's Penydarren Locomotive of 1804, the first locomotive to pull a load along rails; discover the roots of the Labour movement, from the Merthyr Rising of 1831, and the martyrdom of Dic Penderyn, to the first Labour MP - Keir Hardie; see our 'museum of a museum' including curiosities from around the world - ancient Egyptian grave goods, Greek and Roman artefacts, and Far Eastern decorative arts.

Enjoy the elegant surroundings of this interesting museum and once family home, set in beautiful parkland, on the edge of the Brecon Beacons National Park.
