Ottoman Great Bombards

Timeline

1. c. 1400–1452Edirne · EdirneThe Ottomans recruited European gun-founding craftsmen at Adrianople and elsewhere to cast large bronze guns with calibers exceeding 60 cm for bombarding Byzantine fortress walls, drawing technical knowledge from Hungarian and German traditions.
2. 1453Walls of Constantinople · ConstantinopleUrban cast the giant siege gun "Basilica" and others for Mehmed II, continuously bombarding the Theodosian Walls with stone shot; despite slow reloading and some barrels bursting, the guns, combined with mining and the fleet, ultimately brought about the city's fall.
3. c. 1480–1522Rhodes · RhodesFrom the late 15th to early 16th century, the Ottomans continued to deploy large mortars and siege guns in sieges such as Rhodes, Belgrade, and Mohács; siege firepower remained an important tactical means under Bayezid II and Selim I.
4. 1501–1600Dardanelles Strait · Dardanelles StraitThe giant bombards were difficult to transport, had a low rate of fire, and carried a high risk of bursting; after the 16th century, field and siege operations relied more on numerous smaller-caliber bronze and cast-iron guns, while giant mortars were relegated to fortress defense or ceremonial casting.
