Once the Alpenrose hotel, this grand building opened in 2012 as a museum chronicling the history of the Wittelsbach kings and queens, from the 11th century to the present day. Focusing primarily on King Maximilian II and his son Ludwig, it tells the story behind their neighboring castles. The influence of the Wittelsbach family in the region, from the development of Munich, their founding of the first Oktoberfest, and the family's role as resistors of the Nazi regime and
their eventual imprisonment during World War II, are detailed. The interactive exhibits couple state-of-the-art technology with the gold and gilt belongings of the royal family. The café overlooking the lake is the good spot to relax and take in the views after a day of castles.
