New research is currently being carried out in order to collect supplementary data, both historical and archaeological, on the road networks of Medieval Bilād al-Šām and their related facilities. Supported by the material evidence of caravanserais, the aim of the research is to propose a reconstruction and a preliminary analysis of the region's communication axis from the beginning of the Ayyubid period till the end of the Mamluk. The preliminary character of the reflections offered in this article will hopefully be pursued more thoroughly in the completion of a larger project now in its final phase.
