Residents still pass through Istanbul’s roughly 1,500-year-old Topkapi gate today, using a landmark that once served the city’s defense and trade. In a feature on Istanbul’s historic gates, Anadolu Agency traced the structure’s changing role. Art historian Yasin Saygili said it belonged to the land-wall system built during the reign of Theodosius.

During the Ottoman siege of 1453, Sultan Mehmed II established his camp opposite the gate, where suitable terrain enabled heavy artillery attacks. Residents repaired damaged defenses at night, but Ottoman troops eventually entered through breaches in the walls. Following the conquest on May 29, 1453, the gate acquired a name referring to the cannon fire. It subsequently served as a customs gateway for grain and animal feed.

As the walls lost their military purpose, surrounding land became vegetable gardens that helped feed Istanbul. Repairs following the 1509 earthquake incorporated stones from older structures, leaving evidence of different periods in the gate’s masonry. During the Republican era, the surrounding area housed Istanbul’s bus terminal and a flea market, both later relocated. The gateway itself continues to serve pedestrians.

Key Takeaways

• Topkapi remains a pedestrian passage roughly 1,500 years after its construction.
• The surrounding walls faced intense Ottoman artillery fire during the 1453 siege.
• The gate later served customs trade, while its surroundings became a transport hub.
