The Dulle Griet of Ghent
Dulle Griet is a monumental iron bombard located in the city of Ghent. Because of the original red color, the gun was traditionally also called "rode duyvele" old Flemish for "Red Devil'. The bombard dates from 1431 and was probably made by Jean Cambier, the major arms supplier to the Duke of Burgundy, Philip the Good. She was taken in 1578 along with other weaponry from the city of Oudenaarde and brought to Ghent to be used in the fight against the Spaniards. Whether the gun was stolen or sold is unclear.
Since 1943 the Dulle Griet is a protected monument. The square where the gun is on is called "Grootkanonplein", meaning "Big gun square". You can find it at the "Vrijdagmarkt" in Ghent.
