"New Swanstone Castle" is a 19th-century Romanesque Revival palace on a rugged hill above the village of Hohenschwangau near Füssen in southwest Bavaria, Germany. 

The palace was commissioned by King Ludwig II of Bavaria as a retreat.  Ludwig paid for the palace out of his personal fortune and by means of extensive borrowing, rather than Bavarian public funds. The shy king had built the castle in order to withdraw from public life and it was intended as a home for the king, until he died in 1886. It was open to the public shortly after his death. 

Since then more than 61 million people have visited Neuschwanstein Castle.  Every year 1.4 million people visit "the castle of the fairy-tale king". In the summer around 6,000 visitors a day stream through rooms that were intended for a single inhabitant. 

Neuschwanstein Castle can only be visited within a guided tour.
