The Neptune Fountain is the bottom element of a water feature at the “Mad” King Ludwig II’s Schloss Linderhof in Bavaria, Germany. The Music Pavilion lies on the northern mountainside; water cascades down 30 marbles steps to the fountain, which is visible from the king’s bedroom windows.
“Mad” King Ludwig II of Bavaria built the Venus Grotto at the edge of his smallest castle, the Schloss Linderhof. Ludwig was a big fan of Richard Wagner, the German composer, and had the grotto styled after the first act of Wagner’s opera “Tannhäuser.” Ludwig would float around the grotto in the swan boat, sometimes listening to opera singers that he had invited to perform at the castle. The grotto was outfitted with dynamos (rechargeable batteries) so it was illuminated with slowly changing colors.
I was able to visit the grotto on my first visit to Linderhof in 2007.
