The plan: NOVA and a team of master builders from England,
Germany, France and the United States will reconstruct one of
the most destructive of medieval weapons ever made: a giant
trebuchet. They will raise the weapon in the shadows of Castle
Urquhart, located on the shores of Loch Ness in the Scottish
Highlands.
This is one of the castles that English armies attacked during
Edward I's Scottish campaign 700 years ago. As part of the
campaign, the army was said to have built one of the most
monstrous trebuchets ever. Only its name survives: Warwolf.
