Water and Stone sets out to examine the geological sources of Helston’s exceptionally fine granite buildings and pavements and the relationship between geology and industry that is evident in the town's network of kennels and opes - all features that contribute to its unique sense of place.

On Friday evening urban geologist Dr Ruth Siddall of University College London will give a keynote lecture providing an overview of Cornish granite, where it’s gone in the world and what it has been used for. CAST Café supper from 6pm, booking essential.

Throughout the day on Saturday 25 September Stéphane Rouget and James Pharoah will be working granite in the Helston Town Band building on Church Street. All are welcome to drop in and see them at work between 10.30am and 4pm.

At 10.30am on Saturday morning Dr Ruth Siddall will lead a guided walk exploring Helston’s heritage of fine stone buildings and pavements. In the afternoon, from 2.30 to 6pm, there will be a series of talks by sculptor Dr David Paton, geologist Dr Beth Simons, architectural conservation expert Nick Collins, and artist Richard Wentworth.

At 10.30am on Sunday 26 September there will be a guided walk from Helston up the Cober valley to Trannack Quarry. Meanwhile, at CAST, Dr Ruth Siddall will lead a workshop on geological pigments.
