Which historic area of Istanbul, a World Heritage Site, includes Hagia Sophia?

The historic area of Istanbul that includes Hagia Sophia is the Historic Areas of Istanbul. This UNESCO property covers several historic zones on Istanbul’s peninsula, especially in the Fatih district.

The site was inscribed on the World Heritage List in 1985 and includes the Archaeological Park, the Süleymaniye Mosque area, the Zeyrek Mosque area, and sections of the land walls. Hagia Sophia stands within the Archaeological Park, alongside Topkapı Palace, Hagia Irene, and the Sultan Ahmed Mosque, commonly called the Blue Mosque.

A common mix-up is treating Hagia Sophia, Topkapı Palace, or the Blue Mosque as the answer. Each is an individual landmark, while Historic Areas of Istanbul is the larger UNESCO-listed cultural site that groups them together. The designation reflects Istanbul’s layers of Roman, Byzantine, and Ottoman history.
