Guide to Cyfarthfa
Castle & Park
One of South Wales' most spectacular free attractions. Here's everything you need to know about visiting Cyfarthfa Castle Museum, Art Gallery and the stunning surrounding parkland.
The History
Cyfarthfa Castle is one of the most architecturally striking buildings in Wales. Built between 1824 and 1825 by ironmaster William Crawshay II, the castle was designed to overlook his ironworks — a deliberate display of industrial wealth and power at the height of Merthyr Tydfil's dominance as the iron capital of the world.
The Gothic Revival castle, designed by Robert Lugar, sits in 160 acres of landscaped parkland above the town. Its 72 rooms, battlements and turrets make it one of the most impressive private residences built during the Industrial Revolution — and today it stands as a remarkable testament to Merthyr's extraordinary history.
The castle became a school in 1908 and was later converted into a museum and art gallery. It is now Grade I listed, one of only around 500 buildings in Wales to hold this designation, reflecting its exceptional historic and architectural importance.
