These trebuchets were reconstructed at Castelnaud Castle.

A trebuchet has a long arm, or lever, attached to a heavy counterweight. The arm moves around a fulcrum, which is closer to one end than the other. The counterweight is attached to the shorter end of the lever, and the payload is held in a pouch and a sling attached to the longer side.

To fire the trebuchet, the long end of the arm is pulled down, lifting the counterweight into the air. This gives the trebuchet a lot of gravitational potential energy. While the arm is held in place, the projectile is loaded into a sling. When the arm is released, the counterweight drops, the arm whips through the air, and the payload is launched with great speed toward its target.
