Hidden away in the Neues Rathaus is one of the most stunning libraries in the world, and one of Munich’s best kept secrets. The Juristische Bibliothek is a beautiful art nouveau library decked out with wrought-iron spiral staircases and multiple stories of colourful books popping from the shelves. The wildest part? It’s totally open to the public, but not really for sightseeing. If you want to come read or explore the collections, standard Munich library rules apply (leaving your stuff in lockers outside), but if you want to come for photos and sightseeing, you must do so through a guided tour of the Rathaus.
