Klappentext

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A rock cannon, also known in Welsh as a cerrig cannan, craig cannan, or in the 19th century, craig fagnel (plural: craig fagnelau; Welsh: magnel - gun, cannon), is a rock or boulder which has been bored with holes which can be partly loaded with black powder (gunpowder) and ignited to make explosive sounds during traditional celebrations. They are largely found in the slate quarrying areas of Gwynedd in North Wales (235 sites found up to 2001). Each cannon has a number of holes which may range from 3 to 195 (at Parc Moelyci, Sling, Tregarth).
