This book contains a descriptive gazetteer of all the secular buildings (including industrial sites) known by their surviving remains to have existed within the Crusader Kingdom of Jerusalem. The site descriptions take the form of brief notes with full bibliographical references and location maps, accompanied in most cases by photographs and drawings. The gazetteer is preceded by an introduction that analyzes the range of building types to be found in the Crusader Kingdom, and is followed by a supplementary gazetteer listing other sites as "possibles", "rejects", or "don't knows".
