Lichtenstein Castle is situated on a cliff near Honau on the Swabian Alb, Baden-Württemberg, Germany.
There has been a castle on the site since around 1200. It was twice destroyed around 1300 and fell to ruin.
In 1802, the land came into the hands of King Frederick I of Württemberg, who built a hunting lodge there. His nephew Duke Wilhelm of Urach, Count of Württemberg 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.
