The medieval city is located within a 4 km-long wall. The ramparts of the medieval city, partially erected on the foundations of the Byzantine enclosure, were constantly maintained and remodelled between the 14th and 16th centuries under the Grand Masters. AuthenticityThe medieval city of Rhodes maintains the architectural character and the urban organization of a medieval city as well as its primary building materials. The Scientific Committee responsible for the execution of restoration projects in the Medieval City of Rhodes is supervised by the Ministry of Culture, Education and Religious Affairs. Since Rhodes is a living city, the Ministry of Culture, Education and Religious Affairs cooperates with the responsible bodies (Public, Regional and Municipal), so that the medieval city of Rhodes can maintain its qualitative features as a perpetually evolving historical settlement.
