EXCUSE ME, this is still wrong. He built 3.
Neuschwanstein, literally the inspo for the castles in Disney's Sleeping Beauty and Cinderella
Hohenschwangau, the practical castle
Linderhof, the final, the smallest, and the MOST fab.
Every room is incredible and the park is beautiful, but shoutout to The Bedroom, the biggest room
The Hall of Mirrors, which he probably wandered by candle light because he was a serious night owl
The Dining Room, with a wishing table that lowers to the kitchen, and rises with a crank, returning magically full of food
The Venus Grotto, constructed for the sole use of Ludwig to larp to his heart's content
A full artificial cave, it features a waterfall, fake stalactites, and a custom-designed swan boat floating on an artificial lake. The first electricity in Bavaria was generated here, to change the colors of the stage lights and to power Ludwig's fountain and wave machine.
Now THAT'S ~ β¨β¨ 14 million marks in debt β¨β¨~
