🎬 The wind blows over the millennia-old stones of the St. Romanus Gate. Clinging to the battlements, Byzantine soldiers, dark cloaks billowing in the wind, keep silent watch. Before them, in the distance, the red and green tents of the Turkish army cover the plain like a shroud. The Ottomans are there, within arrow’s reach. But between them and the city stands the invincible Theodosian Wall, built a thousand years earlier. Three lines of walls, a wide and deep moat, towers every fifty paces. No one has ever breached this barrier. And yet, everyone feels it: this time, time is running out.
📜 the Defenses of Constantinople
🛡️ Since the 5th century, Constantinople has been protected by the most formidable walls ever built in the Mediterranean. The defensive system, perfected under Emperor Theodosius II, withstood all invasions for a millennium — until this spring of 1453.
🏰 the Land Wall
From south to north, the Theodosian Walls block the western access to the city, between the Sea of Marmara and the Golden Horn. They are composed of three successive lines: – a deep moat, sometimes filled with water, – a first inner wall, – and a main wall, 12 meters high, flanked by 96 towers. Each tower serves as both a watch post and a defensive battery.

The Strategic Points
On the land wall, one of the most strategic sectors is the Lycus Valley, located between the St. Romanus Gate and the Charisius Gate. This Lycus Valley formed a kind of “basin” where the walls were more exposed, accessible, and fragile. It is there that the Ottoman troops of Mehmed II will concentrate their efforts. Opposite, Giovanni Giustiniani, the Genoese condottiere, commands the resistance with his 700 mercenaries.
🌊 the Sea Walls
The city is also surrounded by defensive sea walls, notably: – along the Sea of Marmara, – and on the Golden Horn, where a giant chain prevents enemy ships from entering the harbor.

🛡️ an Impregnable City
These fortifications protected the city against Arab, Bulgarian, Persian, Russian, and then Turkish armies once before. Even the Crusaders of the Fourth Crusade took weeks to enter — and that, by betrayal, not by brute force. In 1453, many believed the wall would still suffice. But this time, a new enemy approaches: the giant cannon of the founder Urban, and the Ottoman artillery.
