The Bleeding Yew tree at Nevern 'bleeds' an unidentifiable red liquid that has baffled scientists and arborists for years. The liquid trickles down the bole and as it does it congeals and blackens. According to legend, a monk was hung from the tree and it has bled ever since. The man declared his innocence and as he did so proclaimed that: "If you hang me guiltless as I am, the tree will bleed for me". The legend also states that the tree will continue to bleed until a Welshman sits on the throne in Nevern.
