Walls of Constantinople
The walls of constantinople are among Istanbul’s most important historic landmarks. In the past, one of the greatest concerns of any city or empire was protection. Since ancient states did not have the technologies we rely on today, their answer was straightforward: walls. Constantinople, as Istanbul was once known, was no exception. In fact, the Walls of Constantinople were so formidable that they resisted siege for hundreds of years. Today, they remain one of the city’s most significant monuments, reflecting Istanbul’s complex and often bloody past.
History of the Walls of Constantinople
So, when were the Walls of Constantinople built? The answer is not as simple as it sounds. Over time, there were several versions, additions, and extensions to the Walls of Constantinople. The oldest known walls were built by the first Greek settlers around the Acropolis. This was the beginning of the Walls of Constantinople’s long history.
These earliest walls were about 6 kilometers long, while the land-facing section measured only around 1 kilometer. There were 27 towers in total, where catapults were placed. Compared with the walls’ later form, this was only a modest beginning. After the Romans conquered the region, Emperor Septimius Severus rebuilt the city, placing new walls 300 meters west of the original line.
After the year 324, Constantine the Great expanded the city westward, which made new defensive works necessary. This also raises another question: how were the Walls of Constantinople built? According to the historical account in this post, Constantine the Great used 40,000 prisoners of war captured during the wars against the Goths to build the wall.
Besieged but Still Standing
The Walls of Constantinople were built above all for defense. In 410, after the emperor learned that Rome had fallen to the Visigoths, another wall was added in front of the old defenses as a precaution. This fourth wall had 96 towers. At that time, the Walls of Constantinople were 12 kilometers long and 12 meters high.
In 447, a devastating earthquake partly destroyed the walls, which was especially alarming because the Huns were active at the time. The emperor responded immediately by building a second wall in front of the damaged one. The number of towers was also doubled, bringing the total to 192. This powerful defensive system became known as the Theodosian Wall.
The long survival of these defenses is one reason the walls still hold such an important place in the story of the city. They stand alongside other major remains of Byzantine and Ottoman Istanbul, including Hagia Sophia and the nearby historic district around Sultanahmet Square.
Where Are the Walls of Constantinople Today?
Only about 5 and a half kilometers of the Theodosian Wall remain standing today. But where are the Walls of Constantinople exactly? The surviving sections begin on the shores of the Golden Horn, near the Blachernae Palace, and continue toward the Golden Gate and the Sea of Marmara. The current length of the Walls of Constantinople is given here as 22 kilometers. There are also eleven gates along the walls.
If you want to visit the walls, some of the best places to view them are the Chora Church, the Palace of Constantine Porphyrogenites, the Edirne Gate, and the Gate of the Seven Towers. These points help bring the old city’s defensive system into focus and make it easier to imagine how impressive the walls once were.

Who Breached the Walls of Constantinople?
The Walls of Constantinople endured many sieges and attacks. They were so formidable that no medieval force could bring them down for centuries. The Walls of Constantinople were finally breached in 1453 by the Ottoman Sultan, Fatih the Conqueror.
After building massive cannons specifically to break the walls, he laid siege to the city. On May 29th, 1453, artillery fire destroyed the Gate of Saint Romanus. Once a breach had been opened, Ottoman forces entered the city. With that, the Byzantine Empire came to an end.
This turning point changed world history and transformed Constantinople into Ottoman Istanbul. Visitors interested in the conquest period often combine the city walls with sites such as Topkapi Palace, which helps tell the next chapter of the city’s story.
