Ancient City Nicaea-Hagia Sophia

The Ancient City Nicaea-Hagia Sophia in İznik, located in Turkey's Bursa province, stands as a remarkable testament to early Christian architecture and a site of profound historical importance. Once a church that hosted significant councils, it reflects the region's eventful past.
History+
The origins of the Hagia Sophia in Nicaea date back to the 4th century, making it the oldest structure in the ancient city. Its greatest significance came as the venue for the Second Council of Nicaea in 787, one of Christianity's ecumenical councils. Following the Ottoman conquest in 1331, the church was converted into a mosque by Orhan I. Over time, the building fell into ruin but was restored as a museum after the establishment of modern Turkey. Since November 2011, the Hagia Sophia has once again been used as a mosque, initiated by the Turkish Deputy Prime Minister.
