Neuschwanstein castle is a 19th-century Bavarian palace on a rugged hill near Hohenschwangau and Füssen in southwest Bavaria, Germany. The palace was commissioned by Ludwig II of Bavaria as a retreat and as a homage to Richard Wagner, the King's inspiring muse. Although public photography of the interior is not permitted, it is the most photographed building in Germany and is one of the country's most popular tourist destinations.
