Up On the Roof explores traditional equestrian clay ridge tiles that from the middle ages adorned rooflines in Britain and Europe. The practice died out by the early 1800s, and now those last and rare remnants are found mainly in West Country museums. Up on the Roof recounts how Bernard Leach and fellow members of the Old Cornwall Society revived the tradition in the 1920s. Over the last decade memories faded once again, until, in 2014, the Leach Pottery instigated research and response. The effect of these tiles, as architectural adornment, clarifies the role of art in the public realm, where it instils interaction and engagement.
