Historical Churches of Istanbul

Istanbul is a city of different religions side by side for many centuries. Being in the middle of the crossroads between Europe and Asia, many civilizations passed through this piece of land leaving a lot of remains behind. Today you can see the temples of three main religions on the side of each other; Christianity, Judaism, and Islam. Being declared the capital city of the Roman Empire in 4 the century by Constantine the Great, Istanbul also became the headquarters of Christianity. As the same emperor declared Christianity as an officially recognized religion, lots of churches opened in the city and started functioning as places of worship. Since the majority of Ottomans were Muslims, and the population started to increase, some of the churches were converted to mosques. Another development in the 15th century was the expulsion of the Jews from the Iberian Peninsula. Following this event, the Ottoman Sultan invited them to settle in his lands, assuring them that they could live in Istanbul and practice their religion freely. As a result, a lot of Jews in 15 the century to come to the city of Istanbul.

As a result, three religions started to live together side by side starting in the 15 century. Every group had its regions in the city where they could have temples, schools, and whatever they may need as a part of their social life. They could even have their courthouses. If two people following the same religion would have a dispute, they would go to their courthouse. Only in case of a dispute between people having different religions is a problem, Muslim courts would be the place to go as an independent courthouse.

Istanbul is the center of Orthodox Christendom for centuries. That’s why there is a church bearing the title of Patriarchal Church.

In the course of history, there were several patriarchal churches and the seat of the throne changed several times over time. The first and most famous patriarchal church was the Hagia Sophia. After Hagia Sophia was converted to a mosque, the patriarchal church was moved to Holy Apostles Church (Havariyun Monastery).
