Feraklos Castle is a ruined medieval fortress, located on an 85 m-high hill overlooking the village of Charaki. It was originally built in the Byzantine era and captured by the Knights Hospitaller on 20 September 1306, being their first possession on the island that would become their base. By 1408 it was in ruins, and was repaired under the Grand Masters Giovanni Battista Orsini (1467–76) and Pierre d'Aubusson (1476–1503) as a stronghold to protect the area, and particularly watch over the anchorages at the Charaki and Agia Agathi beaches nearby.
After 1470, the Hospitallers abandoned all other fortifications on the island except for Feraklos, nearby Lindos, and the city of Rhodes, which in turn were further strengthened. A decree of 1474 prescribed that the Feraklos Castle was the place of refuge by the inhabitants of the villages of Malona, Salia, Katagros, Zinodotou, and Kaminari when there was danger.
The fort was captured by the Ottoman Empire in 1523 after a long siege, a few months after the capture of Rhodes. The Ottomans did not use the castle and it has since been abandoned.
The fortress has an irregular polygonal layout, with a wall perimeter of 680 m encompassing an area of 1,700 square meters. The northern and western portions date to Byzantine times, but the rest are additions or modifications by the Hospitallers. A single gate and two cylindrical towers survive in the southern portion of the walls, along with a cistern in the interior.
References:The trulli, typical limestone dwellings of Alberobello in the southern Italian region of Puglia, are remarkable examples of corbelled dry-stone construction, a prehistoric building technique still in use in this region. These structures, dating from as early as the mid-14th century, characteristically feature pyramidal, domed, or conical roofs built up of corbelled limestone slabs. Although rural trulli can be found all along the Itria Valley, their highest concentration and best preserved examples of this architectural form are in the town of Alberobello, where there are over 1500 structures in the quarters of Rione Monti and Aja Piccola.
The property comprises six land parcels extending over an area of 11 hectares. The land parcels comprise two districts of the city (quarters or Rione Monti with 1,030 trulli; Rione Aia Piccola with 590 trulli) and four specific locations.
Trulli (singular, trullo) are traditional dry stone huts with a corbelled roof.
