The Byzantine Fortress of Leros
The Castle of Panteli, the most significant fortification on Leros, crowns the summit of Pityki hill, overlooking Platanos. Seek the paved path commencing from the hamlet's neighbourhoods, ascending towards the church of Agia Paraskevi (the island's former metropolitan church). From there, climbing the roughly 500 steps, you will reach the Byzantine fortress of Leros, also known as the Castle of Panagia (the Virgin Mary), which dates back to the 11th century. Built in a strategic location, the castle commands the area's two natural harbours and offers panoramic views of the Aegean Sea. Should you prefer easier access, a road from Panteli leads close to the castle entrance.
Archaeological finds from prehistoric, Hellenistic, and Roman periods attest that the area surrounding the hill has been inhabited since antiquity. The castle was founded during the Byzantine era and is mentioned as early as 1087, when Emperor Alexios I Komnenos granted Leros to Saint Christodoulos, the founder of the Monastery of Saint John the Theologian on Patmos.
Over the subsequent centuries, the Knights Hospitaller bolstered it, shaping its present form with three concentric defensive enclosures that create successive zones of defence around the hilltop. Later interventions occurred during the Ottoman and Italian periods.
Within the castle walls stands the Church of Panagia tou Kastrou (Virgin Mary of the Castle), a site of great religious significance for the people of Leros. Smaller ecclesiastical buildings, water cisterns, and remnants of auxiliary facilities that once served the fortified complex also remain. Restoration of the fortifications and the reconstruction of the theatre inside the castle are currently in progress, aiming to showcase the monument and reintegrate it into the cultural life of Leros.
