Hagia Sophia in Istanbul is a 6th-century Byzantine architectural landmark that served as a cathedral, mosque, and museum.

About this subject

Hagia Sophia (Holy Wisdom) was built between 532 and 537 AD under Emperor Justinian I on the site of two earlier basilicas. For nearly a thousand years, it was the largest cathedral in Christendom until the construction of Seville Cathedral. Its central dome, 31 meters in diameter and 55 meters high, was an engineering marvel: it used pendentives to distribute weight and was illuminated by 40 windows at its base, creating the impression that the dome floated on light.

In 1453, after the conquest of Constantinople by Sultan Mehmed II, Hagia Sophia was converted into a mosque. Minarets, a mihrab, and a minbar were added, and the Christian mosaics were covered with plaster or wooden panels. It remained a mosque for nearly 500 years, becoming a symbol of Ottoman presence.

In 1935, under Mustafa Kemal Atatürk, Hagia Sophia was secularized and turned into a museum, allowing visitors of all faiths to appreciate its mosaics and architecture. In 2020, however, the Turkish government reversed its status to a mosque, sparking debates over the balance between cultural heritage and religion. Despite this, it remains open to visitors, with designated areas for prayer and tourism.

Hagia Sophia influenced Islamic architecture (such as the adjacent Blue Mosque) and Renaissance architecture. Its mosaics, such as the Virgin Mary and Emperor Leo VI, are rare examples of Byzantine art. Located in the Sultanahmet district, it has been a UNESCO World Heritage Site since 1985.
