Church turned mosque. That’s the story of the Theotokos Kyriotissa. This magnificent structure stands as a testament to Istanbul’s layered history.
Theotokos Kyriotissa likely began as a 12th-century Greek Orthodox church. Its name means “Virgin, the Mother of God.” It is also known as the Kalenderhane Mosque. The Theotokos Kyriotissa represents a rare example of a Byzantine church. It features a Greek cross plan topped with a dome.
Imagine the services held here centuries ago. Picture the chanting echoing through the halls. Feel the reverence of the worshippers seeking solace.
After the conquest of Constantinople in 1453, the Ottomans repurposed many churches. The Theotokos Kyriotissa became a mosque. Sultan Mehmet II gave it to the Kalenderi dervishes. It then became known as Kalenderhane. The dervishes used it as a zaviye a religious school. They also used it as an imaret a soup kitchen.
In 1746, Hacı Beşir Ağa, a chief eunuch of Topkapı Palace, further transformed the Theotokos Kyriotissa. He added a mihrab, minbar, and mahfil to fully convert it into a mosque. Despite fires and earthquakes, it was restored several times. It continued to function as a mosque.
The Theotokos Kyriotissa showcases middle Byzantine architecture. It features alternating layers of brick and stone masonry. The original marble decoration still survives. It is similar to what you see at Hagia Sophia and the Chora Museum.
Interestingly, during the Latin Conquest of Constantinople in 1204, Catholic Crusaders used the Theotokos Kyriotissa. They decorated the southern chapel with frescoes depicting the life of St. Francis. These frescoes are now in the Istanbul Archaeological Museums.
Restoration efforts in the 1970s helped determine the church’s original dedication. The discovery of frescoes bearing the word “Kyriotissa” confirmed its dedication to the Theotokos Kyriotissa.
Today, the Theotokos Kyriotissa stands near the Vezneciler metro station. It is close to other landmarks like the Valens Aqueduct and Şehzade Mosque.
The Theotokos Kyriotissa is more than just a building. It embodies the transitions of Istanbul’s history. It reflects the city’s Byzantine and Ottoman past. It is a place where different cultures and religions have left their mark. Take a moment to appreciate the enduring legacy of the Theotokos Kyriotissa.
