Pumhart von Steyr
The Pumhart von Steyr is a medieval large-calibre cannon from Styria, Austria, and the largest known wrought-iron bombard by caliber. It weighs around 8 tons and has a length of more than 2.5 meters. It was produced in the early 15th century and could fire, according to modern calculations, an 80 cm stone ball weighing 690 kg to a distance of roughly 600 m after being loaded with 15 kg of gunpowder and set at an elevation of 10°.
