Artists Walker and Bromwich work with artists from North Wales and the community of Bethesda to tell the story of The Great Strike at Penrhyn Quarry 1900 - 1903, the longest industrial dispute in British history. Descendants of the striking miners and their families, who suffered terrible hardship during the strike, still live in Bethesda and this story is told through their voices. A large inflatable quarry is created and processed into Penrhyn Castle, the former home of Lord Penrhyn, the quarry owner during the strike and inflated in his Great Hall to the sound of the Penrhyn Male Voice Choir, which has its origins at the quarry and played a part during the strike.
