In 1277 Edward I gathered a huge army and marched into Wales to subdue the rebel Welsh princes. A key part of his strategy was to erect a castle wherever his army rested. This title takes a detailed look at the design, development and principles of defence of these Welsh castles, documenting daily life within their walls and the historical events that took place around them. Focusing on key sites, it highlights the varied castle designs ranging from fortifications based on French models to the defences inspired by Constantinople, and is illustrated with eight pages of full-colour illustrations and cutaway artwork.
