At one time, Monolithos Castle was considered one of the most powerful fortresses on Rhodes. Built in 1470, not much of the castle remains today save the external walls.
One thing that does remain, however, is the stupendous view at the top of the hill that overlooks the sea. In order to enjoy the view, hardy visitors will have to climb up via small steep stone steps; the climb is strenuous, so past visitors recommend frequent breaks to rest.
Inside the castle that was built on a former castle, travelers will find two 15th century chapels.
