used to attack castles in the middle ages. It
could hurl heavy objects a huge distance!

Welcome to The Grey Company Trebuchet page.
Here you'll find a lot of pictures and a few
words about these amazing pieces of "leverage
artillery" - strange machines referred to
variously as trebuchets, traction trebuchets,
perriers, petrarias, war wolves, coulliards,
bricoles or even "the witch from whose head the
ropes hang like hair". Some of the page is
devoted to providing background information into
how trebuchets were used "in anger" in times past
- while other parts of the page celebrate the joy
of using them today as a wonderful sporting toy.
I hope you enjoy it all...
