Nanstein Castle (German: Burg Nanstein) is a ruined medieval spur castle above the town of Landstuhl, Germany, which has been partially reconstructed. Built in the 12th century, the red sandstone rock castle was once owned by Franz von Sickingen who was mortally wounded during a siege of the castle in 1523.
