In 1802 the land came into the hands of King Frederick I of Württemberg, who built a hunting lodge there. By 1837 the land had passed to his nephew Duke Wilhelm of Urach, Count of Württemberg, who, inspired by Wilhelm Hauff's novel Lichtenstein , added the current castle in 1840–42. The romantic Neo-Gothic design of the castle was created by the architect Carl Alexander Heideloff.
Today the castle is still owned by the Dukes of Urach, but is open to visitors. The castle contains a large collection of historic weapons and armour. http://en.wikipedia.org/wiki/Lichtenstein_Castle
