Byzantine Sites to See in Istanbul > Churches, Museums, Ruins

With its history dating back to 660 BCE, Istanbul is one of the most important cities in the world. Istanbul came to life as an ancient Greek city named Byzantium and it was named as Constantinople during Roman and Byzantine eras, and it was called Konstantiniyye and Dersaadet during the Ottoman Empire. The official history of Istanbul dates back to 2700 years ago and its historical depth is too deep even for the people living in it let alone the visitors.

The most popular tours among domestic and foreign tourists are usually walking tours that include Sultanahmet and important historical monuments nearby. Undoubtedly, these tours are highly comprehensive and informative. However, we need to note that these general tours include monuments that were built in different periods that reflect different cultural aspects.

Indeed, you can gain much better information and cultural insight if you participate in a tour that focus on the history of Byzantine OR Ottoman Empire exclusively.

  •  Hippodrome

Hippodrome is located right in the heart of Sultanahmet and it’s where chariots raced before 50,000 spectators in Constantinople, the capital of Byzantine Empire.

Chariots were vehicles that had 2 wheels pulled by 4 horses and riding these chariots would require a great amount of skill. The chariots would accelerate on the even part of the track and they would skid badly on the corner and the skills of riders would be tested on this part of the track.

Emperor would watch these races himself in his lodge and these races would also witness some important events. The biggest rebellion in Istanbul, the Nika Revolt, started here and it spread to the whole city.

  • Hagia Sophia

Only few people know that the Nika Revolt is the reason why Hagia Sophia was built. Emperor Justinian survived the rebellion that claimed the lives of 30,000 people and he began to build majestic monuments to prove his power. Thus, Anthemius and Isidore, whom the Emperor put in charge, built the biggest and most beautiful sanctuary in the world.

Hagia Sophia is such an astonishing monument that it took a thousand years to build monuments that could be compared to it. In Europe, such monuments began to built in the Renaissance. And in the East, Mimar Sinan built mosques that could be compared to Hagia Sophia one thousand years after Hagia Sophia was built.

It’s really hard to summarize Hagia Sophia in a few words. Therefore, I recommend you to read the posts Hagia Sophia Architecture and Hagia Sophia Mosaics.

Hagia Sophia

  • Hagia Irene

You reach the first yard of Topkapi Palace when you pass by the monumental gate named Bab-i Humayun. This amazing structure from the Byzantine era will be the first monument to welcome you.

Hagia Irene stands out as one of the monuments where one of 7 ecumenical councils met, which founded the base of Christianity. During its hundreds of years of history, this structure witnessed the most magnificent periods of both Byzantine and Ottoman era and it’s also the first archeological museum of Istanbul. Pieces that were displayed here in the 19th century were moved to Istanbul Archeological Museum once it was opened.

  • Basilica Cistern

Istanbul faced a lot of sieges in its long history. Constantinople was one of the most magnificent cities in the Middle Ages and it boasted richness that attracted various civilizations and barbaric tribes.

The famous Walls of Constantinople (Theodosian Walls) were built in the 5th century and they managed to protect the city for centuries. There are only two instances when the city defense failed, the Sack of Constantinople (by Crusaders in 1204) and the Fall of Constantinople (by Ottomans in 1453).

The most essential need of this city that was sieged numerous times and stayed under siege for months was drinking water. As there was no natural water source under the Old City in Istanbul, cisterns, where water was stocked, played an important role. Therefore, Istanbul’s underground was dug numerous times and tens of cisterns were built.

The most famous cistern among many others is Basilica Cistern. This cistern was built with the reused columns from the ancient Greek era. The mysterious atmosphere of Basilica Cistern is a place of attraction for movies that are narrated in Istanbul. Many famous movies such as James Bond and Inferno used Basilica Cistern to shoot parts of the movies.

There are four more Byzantine Cisterns in Sultanahmet area apart from Basilica Cistern. The first two of these cisterns are the Cistern of Philoxenos (Binbirdirek Sarnici) and Theodosius Cistern (Serefiye Sarnici) that has been renovated and opened to visit recently.

Sarnic Restaurant (Sogukcesme Street) and Nakkas Rug Store (Nakilbent Street) are worth visiting too. Please note that these two establishments are managed by private companies. You may also check Byzantine Cisterns in Istanbul post for more information.

  • Valens Aqueduct

When Istanbul was founded as a Greek colony (Byzantium), it was a small city and it had the chance to meet the water need of its citizens by temporary methods.

However, after the Roman Emperor Constantine declared Istanbul as the new capital of the empire, the population of the city grew quickly. The Romans were unable to find water sources nearby and they managed to bring drinking water to Istanbul by constructing the longest water aqueduct of history.

This aqueduct would provide water to the city continually due to its inclined structure. And the need to stock a high level of water required building tens of cisterns. Valens Aqueduct continued to be used during the Ottoman era and it began to be called Bozdogan Kemeri.

However, the Ottomans didn’t fill the cisterns with the water from the aqueduct. Instead, they build monumental drinking fountains and they made access to drinking water easier.

  • Kariye Museum (Chora Church)

Chora has a special place among other structures from the Byzantine era in Istanbul. The reason why it’s special is the finest example works of mosaic art can be found in this church.

You can see tons of Byzantine mosaics at Hagia Sophia too, but the mosaics at Kariye Museum are both better preserved and they are more interesting as there is a story behind them.

Chora Church’s main hall is quite simple and there is only one mosaic panel there. However, the mosaics in the interior and outer corridors of the church are invaluable works of art. These mosaics depict the lives of Jesus Christ and the Virgin Mary. Although they have been damaged by earthquakes, they are still in great condition.

Chora was a monastery and it was outside Emperor Constantine’s Istanbul. This was where monks secluded themselves. However, when Emperor Theodosius II extended the walls, this monastery stayed within the borders of the expanded city. The monastery is still known as “Chora” which means “outside the city” and it also served as a mosque for a short period of time.

The person who was the one helping this monastery gain importance is a Byzantine statesman and scholar named Theodore Metochites. He spent his wealth on decorating this church and he was buried in the section named “parekklesion”, a side chapel built later.

This Byzantine monument is visited by both local and foreign visitors and it’s definitely one of the works of art in Istanbul that are worth visiting.

  • Zeyrek Mosque (Monastery of the Pantocrator)

Monastery of the Pantocrator is located in Zeyrek, one of the historical neighborhoods of Istanbul. This church had  been closed for long years due to restoration and it stands out as the biggest monument after Hagia Sophia among Byzantine churches in Istanbul.

This monument used to serve as the mausoleum of late Byzantine emperors and it was a prominent sanctuary of its time. Hagia Sophia, Church of the Holy Apostles, and Monastery of Christ Pantocrator were the holiest sites in Constantinople.

In order to enjoy the majestic architecture of Zeyrek Mosque, you need to see it from the Golden Horn. When you look at the Old City from the metro bridge on the Golden Horn, it’s one of the most visible Byzantine monument in Istanbul.

  • Walls of Constantinople

Istanbul became the capital of Rome by Emperor Constantine’s order in 330 AD and the borders of Byzantium quadrupled. Thus, the population of Istanbul boomed as Constantinople became the most important city of the East and the walls of the city had to be extended as a result.

Theodosius II wanted to solve the city’s capacity problem as a young emperor and for this purpose he started building the walls. The wise statesman Anthemius, who guided the child emperor, had a great role in the design of these magnificent walls.

The newly built city walls surrounded Constantinople and made the city impenetrable. Constantinople remained as the capital of the Byzantine Empire thanks to the strength of the walls and the security layers of these walls.

It was possible to penetrate these city walls that stretched from the Golden Horn to the Sea of Marmara only after the invention of huge cannons. The army of Mehmet II used these new cannons in the 15th century and they opened a space on the walls, which made the conquest of the city easier.

In order to study the features of Byzantine Walls, you have to drive to the outskirts of Old City. It might be a difficult task but definitely worth it. This medieval wall is definitely one of the most striking Byzantine monuments in Istanbul.

  • Forum of Constantine

The main road of the city in Emperor Constantine’s era was known as “Mese”. The victorious Roman armies returning from a campaign would march on this street, which also housed a square named the Forum of Constantine. Today, this square is known as Cemberlitas and it has a porphyry column which was erected by Constantine.

Two squares were the heart of the city. One of which was the Forum of Constantine and the other one was the Forum of Theodosius. Mese still remains as one of the main roads in the Old City and it’s known as “Divanyolu Street”, on which the tram runs. The reason why it’s named as Divanyolu Street in the Ottoman Empire era is that this road would end up at Divan-i Humayun (Imperial Council) in Topkapi Palace.

If you have a chance to see how the Forum of Constantine used to look, you will realize instantly how exciting it was and it used to be a symbolic center like Taksim Square today.

  • Hagia Theodosia Church (Gul Mosque)

Participating in a Fener Balat walking tour has become a popular activity in recent years. These neighborhoods can be visited on foot in a few hours and you can also take a break at recently opened great boutique cafes opened here. These tours mostly start at Cibali and cover Fener and Balat, but some may extend to Ayvansaray.

We can easily say that Gul Mosque (formerly known as Hagia Theodosia Church) is one of the most beautiful monuments that you will see in your Fener and Balat tour.

This church was dedicated to a deeply pious woman who was martyred during the Byzantine Iconoclasm period. She was believed to have a healing power on people. Therefore, sick people, even on their beds, would be taken to this church for prayers.

The church was decorated with roses on ferial days and the Ottoman army found this church covered with red flowers when they entered the city. Therefore, this place began to be called Gul (Rose) Mosque after it was converted to a mosque.

  • Church of Saint George

The Ottoman Empire allowed Ecumenical Patriarchate of Constantinople to continue its activities after the conquest of Istanbul. Mehmed the Conqueror granted Patriarchate some privileges and it was the religious center of the Orthodox people, the biggest non-Muslim community in Ottoman Istanbul.

Hagia Sophia had been the most important church of the city during the Byzantine era but after it was converted into a mosque, the Patriarchate had to move to a new place. The Church of the Holy Apostles, the second biggest church of its time, was the first address of the Patriarchate. However, as it was demolished later, the Monastery of Pammakaristos began to used as the Patriarchate building.

Finally, the Greek Orthodox Patriarchate moved to the Church of St George in the 16th century, which is still where it is located. The Patriarchate is located in Fener and it’s one of the most important places to visit during Fener and Balat walking tours.

Another amazing work to see at the Patriarchate is the golden altar, which is at the Church of St. George located at the heart of the Patriarchate. Church of St. George is also one of the most important Byzantine style monuments in Istanbul.

Church of Saint George

Church of St. George is not a building from the Byzantine period in its current form. However, someone who studies the Byzantine history should not pass without seeing this place. Because in the church there are relics of the most important bishops of early Christian history.

  • Phanar Greek Orthodox College

As I mentioned above, the Patriarchate continued its activities in Istanbul under the Ottoman Empire. And Phanar Greek Orthodox College was built to supply the demand for the new priests that the Patriarchate needed. Although its location changed for a couple of times, the school usually remained at Fener.

Phanar Greek Orthodox College was one of the best schools of its time and it not only trained priests but also statesmen. The kids of Byzantine origin families in Fener neighborhood served as the special interpreters of the Sultan and Grand Vizier in the Ottoman Empire.

The Greek served as a bridge between Europe and the Ottoman Empire for ages and they were appointed as governors at cities like Wallachia and Bogdan in exchange for their service.

Konstantin Dimadis, one of the graduates of this school, became an architect in the 19th century and he wanted to pay back the community he grew up in. Therefore, he rebuilt Phanar Greek Orthodox College as we know today by donations. Dimadis showed a special effort to make it look like a Byzantine building and he ordered the red bricks covering the outer part of the school from Marseille.

Today, Phanar Greek Orthodox College is not a school that trains priests. It’s a school under the Ministry of Education in Turkey and it provides formal education to the Greek origin students.

Next to Phanar Greek Orthodox College stood Yuvakimyon Girls High School. However, once it shut down due to the lack of students, the girls from Yuvakimyon continued their education at this school too, which turned it into a school providing education to both boys and girls.

Phanar Greek College

Phanar Greek College is not a building from the Byzantine period either. However, it is a structure that offers many clues about the place of the Byzantine people in the city life after the 15th century.

Byzantine Sites Worth Visiting in Istanbul

The names above are only some of the works from the Byzantine era. There are many other Byzantine churches that were converted into a mosque in the city. Almost all of these churches are in Fatih District (Historical Peninsula).

Especially, Suleymaniye, Vefa, Zeyrek, Fener, Balat, Ayvansaray, and Edirnekapi are the places you can find such small Byzantine churches. If you want to review the most important churches in Istanbul’s history, you can read my article called Byzantine Churches of Constantinople.

Byzantine Palaces in Istanbul

Apart from the monuments listed above, there are some other Byzantine artifacts that are about to disappear as they are turning into a ruin. These ruins are mostly the Byzantine palaces in Istanbul. The two main Byzantine palaces in Istanbul were the Great Palace of the Roman Emperors in Sultanahmet and  Palace of Blachernae in Golden Horn.

You can see some of the breathtaking mosaics left from the Great Palace at Istanbul Mosaic Museum inside Arasta Bazaar in Sultanahmet. As you can enter the museum with a Museum Pass, you can visit it without extra payment.

And the Palace of Blachernae was a building where Byzantine emperors resided after the 10th century. It was located on the corner where the Walls of Constantinople and Golden Horn met. Unfortunately, not much has remained from the Palace of Blachernae to the present day.

The Palace of the Porphyrogenitus, the only section remaining from the Blachernae, has recently been converted into a museum. You can visit this building, which is known as Tekfur Palace in Turkish, to study the late Byzantine architecture.
