Lichtenstein Castle is a privately owned tourist attraction built in Gothic Revival style and located in the Swabian Jura of southern Germany. It was designed by Carl Alexander Heideloff and has been described as the "fairy tale castle of Württemberg." It overlooks the Echaz valley near Honau, Reutlingen in the state of Baden-Württemberg. The modern castle was inspired by the novel Lichtenstein (1826) by Wilhelm Hauff and was built in 1840-1842.
