Timeline

  1. 1421–1450Bursa–Edirne cannon foundries · Ottoman EmpireUnder Murad II, the Ottomans had established cannon foundries in Bursa, Edirne, and elsewhere, gradually deploying bronze cannon in Balkan sieges and laying the technical and organizational groundwork for casting giant siege cannons.
  2. c. 1452–1453Edirne · Ottoman EmpireThe Hungarian cannon founder Orban, commissioned by Mehmed II, cast a bronze giant cannon of unprecedented caliber in Edirne; a single gun weighed over ten tons and required teams of dozens of oxen to transport, making it one of the largest known field siege weapons of its time.
  3. 1453Constantinople · Byzantine EmpireDuring the 1453 siege, the giant cannon continuously bombarded the Theodosian Walls, working in concert with numerous medium and small cannon to accelerate the walls' collapse, becoming a key case of cannon ending the medieval castle defense system.
  4. c. 1453–1600Mediterranean–Central Europe · MediterraneanNews of Constantinople's fall and the giant cannon's power prompted Italy and other regions to develop star-shaped bastions and low, thick-walled defenses, spurring the rise of modern fortress engineering, while giant bronze cannon were gradually replaced by more numerous and lighter wrought-iron guns.
