"This book is the result of two most interesting, if rather laborious, journeys, devoted to castle-seeking, one in 1924, covering Wales and the English counties along the Welsh border; the other in 1925, devoted to Somerset, Devon and Cornwall. [...] Of eighty castles described in full, all but six were carefully inspected, and recorded by my own note-book and my son's photographs. [...] The object of this book is to explain the historical and architectural interest of each castle, so that the visitor may appreciate its meaning." -- v, Preface.
