There are 2 castles close together. Hohenschwangau was built on top of a 13th century castle ruin by Ludwig II’s father and the fairytale castle (Neuschwanstein) was built by Ludwig II, also known as “crazy Ludwig” (found insane after bankrupting the family and then mysteriously died). This castle here is probably the most famous icon of Germany and is really amazing to see, though both castles are expensive to enter. Best to book Neuschwanstein a month in advance so you get a good visit time. With both castles you only get a 45 or so minute tour so it isn’t really anything close to the in depth tour of the Munich Residence.
