Tree / House

[Image: A tree turned into architecture by the addition of a door. Photo via Tumblr, where it is erroneously described as being on the Portuguese island of Madeira; in fact, it appears to be a tree on the U.S./Canadian border, as per a shot called "Two boys at the doorway of their treehouse, c.1870-80," from Bridgeman Images, where it is described as a "picture taken on the American/Canadian border." That photo clearly depicts the same tree, albeit at a different stage in its life].
