Housed in the Altes Schloß, the state museum holds an astounding collection of art, design items, jewels, statues, weapons, glass, games (old playing cards featuring birds, dogs, stags and ducks and a 17th Century backgammon board) that make you say wow, eugh, laugh out loud or shake your head in wonder. Explore the castle, the towers and don’t miss the Crown Jewels. Fantastic.
