"Many a book is like a key to unknown chambers within the castle of one’s own self" - Kafka

The castle belonging to this snail is based on Schloss Neuschwanstein in Bavaria, Germany. It was commissioned by King Ludvig II, a product of his own imagination, inspired by "old German knight's castles" and the music of Richard Wagner, and a place that he could retreat into. Inside the castle, the walls were decorated with murals based on the legends used in Wagner's operas. 

His cousin Elizabeth said of him: "The King was not mad; he was just an eccentric living in a world of dreams."

(Neuschwanstein later inspired Walt Disney's Sleeping Beauty Castle at Disneyland.)
