Hagia Sophia, Turkey

Officially known as the Hagia Sophia Grand Mosque, this mosque and former church is a significant historical and cultural landmark in Istanbul, Turkey. Completed in AD 537, it was the final of three church structures that the Eastern Roman Empire erected on the site in succession. It was one of the first to use a fully pendentive dome and the largest interior space in the world.
It has "changed the history of architecture" and is regarded as the pinnacle of Byzantine architecture.With the exception of 1204–1261, when the Latin Crusaders established their own hierarchy, Hagia Sophia functioned as the cathedral of Constantinople in the Byzantine liturgical tradition from its dedication in 360 until 1453.It functioned as a mosque during the fall of Constantinople in 1453, and its minarets were constructed soon after. In 1935, the location was turned into a museum; in 2020, it was renamed a mosque. By 2024, the mosque's upper floor was once again used as a museum.


The Greek geometers Isidore of Miletus and Anthemius of Tralles planned the existing building, which was constructed between 532 and 537 by Byzantine emperor Justinian I as the Christian cathedral of Constantinople.The third church of the same name to occupy the site, the first having been destroyed in the Nika riots, it was officially known as the Church of God's Holy Wisdom. Before the Seville Cathedral was finished in 1520, it was the greatest cathedral in the world for almost a millennium as the episcopal see of the ecumenical patriarch of Constantinople.A thousand years later, Ottoman mosques imitated the architectural style of Hagia Sophia, which became the archetypal example of Eastern Orthodox church architecture. Numerous other religious structures, such as the Hagia Sophia in Thessaloniki, Panagia Ekatontapiliani, the Şehzade Mosque, the Süleymaniye Mosque, the Rüstem Pasha Mosque, and the Kılıç Ali Pasha Complex, were inspired by the Hagia Sophia's architecture.
