Part of an international series of amply illustrated, colorful, small size books for children ages 5 to 10, this volume outlines the step-by-step process of building a cathedral in the Middle Ages. Terms are defined and artisan techniques explained for each step on the way to building the edifice. The text also relates the story of how families lived in the 12th and 13th centuries and the role the cathedrals played in their lives. Drawings and explanations of terms such as flying buttresses, professions such as stone carvers and joiners, and details of the construction are included. (NL)
