Basilica of St. Stephen

The Basilica of St. Stephen is a Byzantine church whose remains now form an archaeological site on the island of Kos. Through the medieval centuries it served the local community as a place of worship, and its ruins stand as a notable example of religious architecture from the Byzantine period. Its setting within the Municipality of Kos reflects the island’s strategic and spiritual importance in Byzantine times, when coastal positions in the Aegean carried real weight for trade, defense, and the life of the church.
