The fortunes of Byzantine Constantinople have always been inextricably linked to the sea. The topographical, demographic and economic development of the city and its networks are reflected in the history of its harbours. This volume offers an exhaustive study of Constantinople's Byzantine harbours on the Sea of Marmara and the Golden Horn, as well as nearby European and Asian landing stages. The fifteen chapters by eleven contributors here present a broad synthesis of the current state of research using written, pictorial and archaeological sources.
