Hagia Sophia, which was built as a basilica since the 4th century AD, was reorganized after earthquakes during the reign of Justinian. The building has a 3-nave narthex layout, representing the architectural blend of the early Byzantine period.

The building, which was converted into a mosque with the conquest of Iznik by Orhan Gazi in 1331, underwent a major restoration by Mimar Sinan in the 16th century, and a mihrab and pulpit were added.

Today, it welcomes its visitors both as a museum that reveals the historical heritage and as an active place of worship.
