Castle built on a rock on the ridge of Mount Atheras on the northeastern side of Ikaria island in altitude 810 meters. There is no indication about when it was built or for what purpose or by whom.

Structure, Fortification & Buildings

The castle is built on top of a rock measuring approximately 70mx30m. Within the castle there are neither remnants of buildings or shells or other surface finds. On the south side, outside but close to the fort, there are several ruined buildings.

It is possible that this was a project that never finished. However, its location and the dimensions of the walls (preserved height up to 3,50m., Thickness up to 1.70m.) show that it was not was just a makeshift construction.

The most probable theory is that this was a castle-refugee built around the 16th century for the protection of the population from the pirates. It must have been used only occasionally, during pirate raids.
But this is only a theory, we cannot know for sure.
