Additional info

Castell Pridd Farm is 8 miles north of Cardigan just off the A487 Cardigan to Aberystwyth main road.We are just to the north of the village of Tanygroes, 300yds down the Betws Ifan road.

Castell Pridd is marked on the OS Map for Ceredigion.

The collection covers early oil engines through to gas turbines but with the emphasis on diesel power from the 1920s to the 1960s.

The museum runs engines 7 days a week during the summer months and by arrangement in the winter period. The intention is to create a display as near to the original working environment as possible so that vistors can see, smell and hear what these engines did.

Key artists and exhibits

  • Most, eventually we hope all, major UK manufacturers are represented with engines from Tangye, Petter, Ruston Hornsby, Allen and Belliss & Morcom.
  • In 2005 a 1912 air blast Sulzer diesel was installed. This is one of the earliest regularly run production diesel engines in the world.
  • After a lot of work, in 2006 our Worthington-Simpson two-stroke diesel became full operational. This is an example of the first solid injection diesel engine to be built in the U.S.A.
  • 2008 will see the first running of the 30 ton Ruston 6VE diesel from the BBC Moorside Edge Transmitter built in 1930.
