Adding coins to these trees, most of which are located in the North Yorkshire forests, is a centuries old tradition. At the ruins of Saint Maelrubha wishing tree, there's a coin dating all the way back to 1828.
While many of these wishing trees are fallen,dead trunks and stumps, some are living, which can be harmful to the tree. Still, new coins are appearing in these trees still today, as many voyage to them to cast their wishes.
Arborsculpture is "the use of living trees to create a desired shape or structure." There are several methods used to shape trees while they are still living and growing into different sculptures and designs. While used for artistic purposes, arborsculpture can also be used to form functional root bridges.
Poland's Crooked Forest is similarly breathtaking, but this interesting collection of curved trees appears to be naturally occurring. There are several theories as to why these trees began growing this way, but the most popular idea is that they were actually shaped by man at one point. Similar to arborsculpture, many believe farmers in the 1930s manipulated the trees this way for better construction, furniture and ship building material.
