The Pumhart von Steyr (lit.'Styrian Bombard')[1] is a medievallarge-calibre cannon from Styria, Austria, and the largest known wrought-ironbombard by caliber.[2] It weighs around 8 t (7.9 long tons; 8.8 short tons) and has a length of more than 2.59 m (8 ft 6 in). It was produced in the early 15th century and could fire, according to modern calculations, an 800 mm (31 in) stone ball weighing 690 kg (1,520 lb) to a distance of roughly 600 m (2,000 ft) after being loaded with 15 kg (33 lb) of gunpowder and set at an elevation of 10°.[3]
Besides the Pumhart von Steyr, a number of 15th-century European large-calibre weapons are known to have been employed primarily in siege warfare, including the wrought-iron Mons Meg and Dulle Griet as well as the cast-bronze Faule Mette, Faule Grete and Grose Bochse.
