Rhodes. Greece. View of an outdoor stone staircase at 14th century Byzantine monastery. The monastery structures which were originally built by the Knights of St John were all realistically restored by the Italians during their occupation of Rhodes in the early 20th century. Situated on the acropolis of Mt Filerimos on the verdant windswept west coast of Rhodes, Ialyssos is an outstanding fusion of ancient Doric, Byzantine and medieval archaeological remains and is one the finest sites of Rhodes Island. The island of Rhodes is the largest of the Dodecanese Island group and one of the most popular Greek Islands.
