The Visible Sound Collection

This is the story of Mrs Watts-Hughes, a Dowlais born vocalist, who made the human voice visible and became the first woman to display a scientific instrument of her creation at the Royal Society in London. This is a collection of what she called ‘Voice Figures’ that are held at Cyfarthfa Castle. 

The Southey Egyptian Collection

A brief look at an amazing collection of objects given to Cyfarthfa Castle Museum and Art Gallery by Harry Southey.

WWII Photographs of Idris Hancock

Cyfarthfa Castle has an amazing collection and as today marks the 75th Anniversary of VE Day we thought we would show you a collection of photographs. This is a collection of photographs that once belonged to Idris Hancock, who lived in Merthyr Tydfil and served with the Royal Army Service Corps in the Middle East.

About the Museum

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”.

The museum houses the first steam whistle, the first voting ballot box and dresses by Laura Ashley and Julien McDonald.  The surroundings, Cyfarthfa Castle, home to William Crawshay II and family, serve as a reminder to the Ironmasters dominance over the town and the wealth the iron industry brought to the area.

At the Castle you can admire the extensive fine and decorative art collections.  This includes Swansea, Nantgarw and Wedgwood porcelain and art by Penry Williams, the Welsh Turner, and George Frederick Harris.

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. 

Finally, see our curiosities from around the world including Ancient Egyptian grave goods.
