A trebuchet is a type of medieval siege engine used to hurl projectiles at enemy fortifications. It operates on the principle of leverage, using a long arm to launch stones or other heavy objects over great distances. Trebuchets were effective in breaking down walls and causing destruction during battles. These machines were typically made of wood and could be quite large, requiring a team of people to operate. The design of a trebuchet allowed for greater accuracy and power compared to earlier siege weapons, such as catapults. They played a significant role in warfare during the Middle Ages.
