Together with the Minster, the walls and bars make York one of the most instantly recognisable cities in the kingdom. The defenses are the most complete in England, with the walls set upon high ramparts and retaining their principal gateways. Although the walls are still standing, there has been relatively little opportunity for archaeological investigation, so documentary and pictorial evidence are of paramount importance. York is fortunate in possessing excellent collections of both. The book outlines the historical background from the pre-Conquest defenses to the present day and considers the walls, bars and posterns, the Old Baile and the castle in detail. It is a splendid and well-illustrated publication that will appeal to anyone interested in the history of York, military history, art, architecture or archaeology.
