This volume brings together 22 of the papers presented at a conference held in Esztergom, Hungary, in May 2018 to coincide with the 800th anniversary of the crusade of King Andrew II of Hungary to the Holy Land in 1217-18. The theme, Bridge of Civilizations, was chosen to highlight aspects of the links and contrasts between Europe and the areas around the eastern Mediterranean that were visited and occupied by western crusaders and settlers in the twelfth and thirteenth centuries, giving special attention to the evidence provided by archaeology and material culture, as well as historical sources.

The results of the joint Syrian-Hungarian Archaeological Mission (SHAM) to the Hospitaller castle of Margat (al-Marqab) highlighted in this volume include an up-to-date overview of the structural development of the site from 1187 to 1285, as well as particular studies of the wall paintings, cooking installations and pottery. SHAM's recent rescue work at Crac des Chevaliers also provides the basis for studies of the water-management system and medieval burials revealed in its courtyard, while other papers examine the masonry marks and surviving evidence of medieval trebuchet damage at both castles. Other papers focus on the medieval castles of Karak (Jordan) and Jubayl (Lebanon), the medieval buildings of Latakia (Syria), the impact of the Crusades on buildings in Cairo, historic bridges in Lebanon, the medieval chapels of Yanouh-Mghayreh and Edde-Jbeil (Lebanon), piscinas in Crusader churches in the East, the images of donors found in medieval Lebanese churches, and the activity of late thirteenth-century Western metal-workers in Cyprus.

Papers focusing more particularly on historical sources include a new edition of a late eleventh- to twelfth-century pilgrimage itinerary from Hungary to the Holy Land, a discussion of two minor military orders in Hungary, and the portrayal of Sultan al-Kāmil in a contemporary western account of the Fifth Crusade.
