A short trail through the woods leads to the ruins of the Three Castles—more like three towers, really—that are perched on a ridge above Eguisheim, Alsace, France. The structures date to the 1200s, and they were “destroyed in 1466 in the ‘Six Deniers War'” [according to the signage]. Memo to self: look up the Six Deniers War, it sounds very Game of Thrones-like.
