Throughout the island of Rhodes, forts and castles designed to protect the inhabitants from enemy attacks, were constructed on strategic, since antiquity, sites. Above the bay of Haraki – today a small resort – the view is dominated by the ruins of the impregnable medieval castle of Faraklos, at the foot of which, the remains of an ancient sugar mill was discovered, operating since the era of the Knights’ Rule. Near the village of Monolithos, the namesake castle is perched at the top of a huge steep rock, rising within short distance from the coast, offering stunning views. Built by the Knights of the Order of St. John in the 14th c. to controling the sea passage and protecting the residents from pirate raids. The sunset here is enchanting with the road from the castle leading to beautiful secluded beaches. The castle of Kritinia – also known as Kastellos – is a mixture of Byzantine and Medieval styles, with its fortifications enclosing the ruins of the Christian church of St. Paul. During the Venetian rule, it was used as a dockyard. The castle of Asclepeion was built by the Grand Master Pierre d’Aubusson in 1479, at the site of the ancient beacon tower. The castle was used by the Knights and earlier to that by the Byzantines, to protect the residents of the nearby villages with rectangular bastions and two strong towers.
