Hagia Sophia is much more than a magnificent structure rising above Istanbul’s historic peninsula.

This unique structure has left its mark in many areas, from architecture to religion, politics to art, and has acquired a different identity in each period.
In this article, we will take a detailed look at the history, architecture, cultural impact, contributions to humanity, and organization of Hagia Sophia.
The Centuries-Long History of Hagia Sophia
Hagia Sophia was built in 537 AD by order of Byzantine Emperor Justinian I. It was an awe-inspiring structure not only for its time but even by today’s technological standards. Approximately 10,000 workers were employed in its construction, which took only five years to complete.

Historical Stages of Hagia Sophia:
- Church Period (537–1453): Hagia Sophia served as the largest cathedral in the Christian world for approximately 900 years.
- Conversion into a Mosque (1453–1935): It was converted into a mosque after the conquest of Istanbul by Mehmed the Conqueror. The mosaics were covered with a thin layer of plaster, minarets were added, and the building was renamed the Hagia Sophia Mosque.
- Museum Period (1935–2020): During the Republican era, Hagia Sophia was converted into a museum. The Hagia Sophia Museum became a symbol that attracted tourists from all over the world.
