Neuschwanstein Castle is a Romanesque Revival palace commissioned by King Ludwig II of Bavaria in 1868. This castle on a rugged hill above the village of Hohenschwangau was intended to be Ludwig's personal retreat, though it was still under construction at the time of his death in 1886. It was soon thereafter opened to tourists, and remains a popular destination. Its architecture has inspired several further buildings, including Disneyland's Sleeping Beauty Castle.Photograph: Thomas Wolf
