Collachium

The name designates the northernmost part of the Medieval City, monopolized by the Knights of the Order of St. John and their activities. Although the origins of this enclave date back to the Hellenistic period, it was during the Byzantine era that its limits expanded, reaching its actual status in the 11th and 12th centuries AD.
The fortifications of the Collachium were actually the frontline of defence, the rearmost line having obviously been the Palace of the Grand Master. At the time of the Knights, the fortifications of the Medieval City was extended so much as to include the urban area, bestowing the city its typical triptych-form defence structure. The Collachium included the Palace of the Grand Master, the Hospital of the Knights as well as the Inns of the various Tongues. It pays to note that circulation within the perimeter of the Collachium during the night used to be closely monitored.
