During World War I and World War II, the castle suffered no damage. In 1923, the Bavarian Landtag recognised the right of the former royal family to reside in the castle. From 1933 to 1939, Crown Prince Rupprecht of Bavaria and his family used the castle as their summer residence, and it continues to be a favourite residence of his successors. In May 1941, Prince Adalbert of Bavaria was purged from the military under Hitler's Prinzenerlass and withdrew to the family castle Hohenschwangau, where he lived for the rest of the war.
