The Museum is closed temporarily in order to complete a major redevelopment, and is taking its story 'on the road' to locations at the heart of the slate story - including here at Penrhyn Castle.

Demonstrations take place daily in the Stable Block at 11am, 12pm, 3pm and 4pm.

*Please note that only assistance dogs are allowed into the slate splitting demonstration room.
