The Arab raids and terror of the mid-7^th century forced most of the locals to inhabitants of leave the defenseless coastline and settle or seek refuge to inaccessible mountainous areas.

Hence, the fortifications on top of Lazarus peak must have been built sometime during the mid-7^th century (Lazarus is a peak of Mount Abelos, overlooking the north and south coastlines and seas, as well as the major plains of the island).

The castle (Dimensions: 380 x 120 meters) is built on a flat plateau on top of the peak. Only parts of the walls and of the main gate are preserved, along with parts of the foundation of the houses and of a small church dedicated to Saint Lazarus (hence the name of the peak).

At that time, these kinds of castles were used in times of pirate or enemy raids or for observation of the ships and boats crossing Samos Strait.

Indeed, from Lazarus peak someone can see and enjoy the magnificent view of the eastern side of the island, with all its towns and villages, while from the highest peak of Mountain Karvounis, called “Prophet Elijah” someone can see and enjoy the entire western side of the island.
