Edessa, the ancient predecessor of modern Şanlıurfa in Turkey, offers a journey through layers of Hellenistic, Roman, and early Christian history. Founded by Macedonian general Seleucus I Nicator around 303 BC and named after an ancient Macedonian capital, this former crossroads city sits on a ridge surrounded by a fertile plain near the Taurus Mountains. You will step into a storied settlement that served as the capital of the Kingdom of Osroene, a Roman frontier stronghold, and a prominent center of Greek and Syriac thought hosting the famed School of Edessa.
As you explore, look for Şanlıurfa Castle, the high central citadel positioned along the Daysan River. You can trace a landscape where early Christian pilgrims journeyed to see sacred sites including the cathedral church dedicated to Holy Wisdom, the Church of St Thomas, and formidable ancient fortifications. The city is also associated with traditions identifying it as Ur of the Chaldees, the birthplace of Abraham.
From its early Assyrian and Aramaic origins to its history as a Crusader state capital, visiting Edessa brings you face-to-face with millennia of rich Mesopotamian heritage.
