Lichtenstein Castle is a privately-owned Gothic Revival castle located in the Swabian Jura of southern Germany. It was designed by Carl Alexander Heideloff and its name means "shining stone" or "bright stone". The castle overlooks the Echaz valley near Honau, Reutlingen in the state of Baden-Württemberg. The modern castle was inspired by Wilhelm Hauff's 1826 novel Lichtenstein and was built in 1840–1842. The ruins of an older medieval castle are a few hundred meters away.
