This castle served as an inspiration to William Shakespeare to white his most famous play, and possibly the most famous play in the history of literature Hamlet, Prince of Denmark. It's located in the little town north of Copenhagen called Helsingør (similarly pronounced as the name of Hamlet's castle 'Elsinore'). At this castle there is an ongoing non-stop play, so you get to meet Hamlet and the rest of the crew, maybe take some photos with him, hey, the guy has his own Wikipedia page, that's gotta count for something. Just make sure to do it before the duel, spoiler alert! He dies.
