Nicaea, Ancient Greek archaeological site in İznik, Turkey.
The ancient city lies on the eastern shore of Lake İznik, enclosed by Roman walls extending over 4,426 meters in circumference with multiple towers.
Nicaea hosted two crucial Christian councils in 325 CE and 787 CE, establishing fundamental doctrines and addressing theological matters of the early Church.
The site contains remains of Byzantine churches, Roman structures, and Ottoman mosques, including the converted Hagia Sophia church, now Orhan Mosque.
Visitors can access the archaeological area through several gates in the ancient walls, which stand approximately 10 meters high around the settlement.
Underwater excavations in Lake İznik revealed a submerged 4th-century basilica, indicating the presence of earlier structures beneath the current water level.
