A German professor, examining records of Ludwig, has diagnosed him with "compulsive castle-building syndrome".
[Ludwig] squandered a royal fortune due to a particular form of megalomania, according to Professor Heinz HÃ¤fner, founder of the Central Institute for Mental Health in Mannheim, a compulsion to build castle after castle after castle. He came to this conclusion upon studying the secret archives of Prince Franz of Bavaria, a descendant of King Ludwig ... The king would get a craving to build, turn all restless and excited, and could only be calmed by drawing up plans and visiting the construction site. After a period of satisfaction, the cycle would start all over again.
