Neuschwanstein Castle is a 19th-century Gothic Revival palace on a rugged hill above the village of Hohenschwangau in southwest Bavaria, Germany. The palace was commissioned by Ludwig II of Bavaria as a retreat and as an homage to Richard Wagner.
The palace was intended as a personal refuge for the reclusive king, but it was opened to the paying public immediately after his death in 1886. Since then over 60 million people have visited the Castle.
The palace has appeared prominently in several movies and was the inspiration for Disneyland's Sleeping Beauty Castle.
