The centre was the first in the world to reconstruct an actual working trebuchet in 1989. Since then the centre has been hired to help build the trebuchet at Warwick Castle, Warwickshire, England which was the largest functioning trebuchet in the world for six years. In 2011 the Middelaldercentret took back the record, putting a longer throwing arm on the machine after the old one broke. The new throwing arm is just 5 centimeters longer than the one on the machine at Warwick Castle.
