Note 296 — Chapter X · THE EDWARDIAN CASTLE AND THE CONCENTRIC PLAN

Viollet-le-Duc’s drawing (La Cité de Carcassonne, p.75) shows a rampart-walk on each of the enclosing walls of this passage. He also shows the passage crossed by a series of looped barriers, so placed that each formed a separate line of defence, guarded by a few soldiers, and compelled an enemy to pursue a zigzag course through the passage. Much allusion has been already made to oblique and elbow-shaped contrivances for impeding an enemy’s progress: the antiquity of these is evident from the entrances to earthworks like Maiden Castle (see Chapter I.).
