Lohengrin (opera)
Wagner’s opera is like a fairy tale.  It immediately became very popular.  The young King Ludwig II of Bavaria built a fairy-tale castle in the south of Germany and called it "Neuschwanstein," meaning: “New Swan Stone”.  The King was very fond of Wagner’s music and gave him a lot of money to help him with his next operas, especially for the cycle known as the Ring of the Nibelung.
