The Location of Constantinople

Understanding the Geography of a Historic City

This article offers a simple overview of the land on which Constantinople was built. While we won’t go into the deep details found in works like that of Petrus Gyllius, it is still important to understand the basic geography before exploring the ruins of what was once called New Rome.

Constantinople lies at the southwestern end of the Bosporus Strait, a narrow waterway that connects the Black Sea to the Sea of Marmara. The city was built on a promontory, a piece of land that juts out into the water from the European side of the strait. The tip of this land faces upstream, as if trying to hold back the strong current flowing from the Black Sea to the Sea of Marmara Sofia City Tour.

Natural Borders and Surroundings

The Golden Horn, the Sea of Marmara, and Asia

To the north of the city lies a long and narrow bay called the Golden Horn. This bay stretches inland between steep banks for about six to seven miles. In ancient times, it was one of the best natural harbors in the world, offering safe and deep water for ships.

To the south, the Sea of Marmara opens up wide like a lake. On the Asian side of this sea, you can see hills, mountains, and small islands. Directly across from the eastern side of the city’s promontory are the historic towns of Chrysopolis (modern Üsküdar) and Chalcedon (modern Kadıköy), both located in present-day Istanbul on the Asian side.

The Western Landscape

A Plain with a Rich Past

To the west of Constantinople, the land becomes a gently rolling plain. Although it does not offer much in terms of striking natural beauty today, in the glory days of the Byzantine Empire, this area was full of villas, gardens, and beautiful homes. It must have been a peaceful and elegant part of the city’s surroundings.

The western plain stretches out toward the horizon and served as the main land route into the city. Over centuries, this land witnessed countless armies, traders, and pilgrims entering Constantinople.

A City Built to Control Land and Sea

Constantinople’s unique position gave it great strategic and commercial importance. It controlled the water route between two seas and stood at the crossroads of Europe and Asia. Surrounded by natural barriers like the Golden Horn and the Sea of Marmara, and facing rich and ancient cities across the strait, the site was perfectly chosen for what would become one of the greatest cities in world history.
