Basilica of Agios Achilleios
On the islet of Agios Achilleios in the Small Prespa Lake, amid stones etched with centuries of history, stand the ruins of one of Greece’s most iconic Byzantine basilicas. Built by Tsar Samuel between 986 and 990 AD to house the relics of Saint Achilleios, the three-aisled, timber-roofed basilica still impresses with its large scale and architectural presence. The stepped synthronon in the apse bears witness to its episcopal character, while in the diaconicon a box-shaped tomb, attributed to the patron saint, is preserved. The surviving fragments of 11th- and 12th-century frescoes further reveal the monument’s later interventions and the different phases it underwent over time. Reaching the site via the pedestrian bridge that crosses the lake is an experience in itself—one that feels like stepping into the past, where nature embraces history.
