The Harbour of All This Sea and Realm offers an overview of Famagusta's Lusignan, Genoese and Venetian history. The essays contribute to the understanding of the city's social and administrative structure, as well as of itsarchitectural and art historical heritage in the period from the thirteenth to sixteenth centuries. The two themes of Famagusta's diasporas and cultural hybridity permeate all of the articles in this collaborative effort and constitute their most conspicuous unifying feature. Some of the studies carry out the harmonization of archival sources and thus manage to reconstruct the early stages of appearances of various buildings. In light of the threats facing Famagusta's medieval and early modern heritage, having been in a zone of military occupation since 1974, such research is of vital importance.
