Whereas a great deal of research has been carried out on Crusader castles, churches and major buildings in the Latin East, almost no attention has been paid to domestic architecture and the domestic settings in which most of the population of the Crusader states spent most of their time. The present work attempts to address this deficiency by taking an in-depth look at the various domestic buildings that served the urban and rural population and the domestic apartments in castles and mosasteries. The basis for this survey is the wealth of published and unpublished archaeological data that has been uncovered over the past century and the various documentary materials available, much of which has been overlooked in the past.
