The ruins of a Roman basilica submerged in a lake in Turkey have resurfaced after spending more than 700 years underwater, revealing a major site from the early Christian world. The structure, long hidden beneath Lake Iznik (Lake Ascania in antiquity), now stands exposed as the lake continues to retreat due to climate change.
The basilica, known as the Basilica of the Holy Fathers, marks the ground where the First Council of Nicaea met, only 12 years after Christianity was legalized in the Roman Empire. In AD 325, Constantine the Great convened the council in the ancient Greek city of Nicaea (Greek: Νίκαια), a major Greek city of the Byzantine Empire (Eastern Roman Empire). A total of 318 bishops debated for two months before drafting the Nicaean Creed, a Greek-language declaration of faith that remains central to Christianity. Pope Leo XIV visited the site on Friday to mark the 1,700th anniversary of the council.
