Hagia Sophia Church Istanbul: An Iconic Symbol of Byzantine Architecture

Hagia Sophia Church, Ayasofya in Turkish, also known as Church of the Divine Wisdom or Church of the Holy Wisdom, is an architectural masterpiece in Istanbul, Turkey.

Being a World Heritage Site by UNESCO, it is one of Istanbul’s most significant and one of the World’s great monuments. 

It was initially constructed as a church, then converted into a mosque, later served as a museum, and now once again is a mosque.

Throughout the centuries, Hagia Sophia has survived the test of time, seen the rise and fall of empires, and bore the brunt of countless disasters.

And all that while steadfastly preserving its remarkable history.

Hagia Sophia Church History

  • Hagia Sophia, known as the Magna Ecclesia, means great church due to its large dimensions in Constantinople, now in Istanbul.
  • First consecrated by bishop Eudoxius of Antioch, Hagia Sophia was inaugurated by Constantius II on 15 February 360.
  • The name Hagia Sophia came into use around 430. Initially, it served as the bishop’s seat, also known as the Cathedral of the city.
  • The initial church was a wooden-roofed Basilica featuring a central nave flanked by two or four aisles, each carrying a gallery story.
  • Different regions within the illustrious Byzantine Empire played an active role in the church’s creation. 
  • Egypt sourced the green marble, Syria provided the yellow stone, and the Bosporus region contributed the black stone.
  • The riots in 404 destroyed the first church structure.
  • Emperor Theodosius II constructed and dedicated a second church in 415.
  • However, it tragically burned down during the Nika Revolt of 532, resulting in widespread destruction and loss of life in the city.
  • The interior of Hagia Sophia incorporated columns from the Temple of Artemis.
  • The Hagia Sophia’s dome construction involved 10,000 workers who dedicated their efforts to its completion.

Byzantine Era

During the Byzantine Era, Emperor Justinian I commissioned the construction of the Hagia Sophia Church in the 6th century AD. 

The architects Anthemius of Tralles and Isidore of Miletus designed and completed it in 537 AD.

The Byzantine Empire intentionally designed the church to symbolize its grandeur and power.

Ottoman Era

In 1453, the Ottoman Empire conquered Constantinople (now Istanbul) and converted Hagia Sophia into a mosque. 

Islamic architectural elements, such as minarets and mihrabs, were added to the structure. 

The church’s mosaics and frescoes were covered or removed, keeping Islamic sensibilities in mind.

Modern Era

In 1935, under the presidency of Mustafa Kemal Atatürk, Hagia Sophia was converted into a museum as part of the secularization efforts in Turkey. 

This decision aimed to preserve the building’s historical and cultural significance, allowing people of different backgrounds to appreciate its architectural beauty.
