|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 an 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. The palace comprises a gatehouse, a Tower, the Knight's House with a square tower, and a Palas, or citadel, with two towers to the Western end. The effect of the whole is highly theatrical, both externally and internally. The king's influence is apparent throughout, and he took a keen personal interest in the design and decoration. An example can be seen in his comments, or commands, regarding a mural depicting Lohengrin in the Palas; "His Majesty wishes that … the ship be placed further from the shore, that Lohengrin's neck be less tilted, that the chain from the ship to the swan be of gold and not of roses, and finally that the style of the castle shall be kept medieval.
