It was the first fortress on Rhodes to be captured by the Knights Hospitaller in 1306.
The castle served as a secure treasury for the Knights Hospitaller during times of conflict.
It acted as a maritime monitoring station capable of communicating with other nearby fortifications via smoke and fire signals.
The interior contains two massive underground cisterns designed to collect rainwater, essential for surviving long sieges.
It was used as a prison for unruly knights and captured enemies, including the deposed Grand Master of the Order, Jacques de Milly.
The fortress was strategically positioned to defend the nearby Agia Agathi cove from pirate raids.
Feraklos Castle is a ruined Byzantine and Knights Hospitaller fortress situated on a 300-meter-high hill overlooking the coastal village of Charaki on the island of Rhodes. It served as a vital maritime lookout point and served as a prison for prominent figures during the Order of St. John's occupation. The fortification was originally Byzantine before the Knights of St. John captured and significantly expanded the structure in the 14th century. After being abandoned following the Ottoman conquest in 1523, the fortress was never resettled. Its defensive layout includes remnants of thick stone ramparts, cisterns for water storage, and the foundations of internal buildings. The site is currently an unmanaged archaeological ruin accessible by a steep dirt trail. It offers panoramic views of the Aegean Sea and the coastline of Agia Agathi beach.

Wear sturdy, closed-toe hiking shoes as the ascent involves loose scree and rocky, uneven terrain.
Bring your own drinking water as there are no facilities or shade once you reach the summit.
Visit during the shoulder seasons to avoid high heat and strong winds common on the exposed hill.
Do not attempt the climb in flip-flops or open sandals, and avoid ascending during high winds.
No formal rules, but visitors should respect the site by not climbing on fragile, unstable stone walls.
