In this video you can see how a long bow is made, based on the specimens found in the shipwreck Mery Rose (1545).
Yew bows have been used since prehistoric times and we have some preserved in the archaeological site of La Draga, in Catalonia.
Yew is a wood where the heartwood withstands compression very well and the sapwood is resistant to traction. This makes it an ideal wood for building powerful bows.
