Hohenrechberg
Hohenrechberg was first mentioned in records in 1355, the castle part of a series of fortresses in the area, this one belonging to the Count of Rechberg.  The current castle is largely as it looked in the 1500s, save for the damage later caused by lightning and fire.  Two dukes fought over this castle in 1554, because one was trying to steal the other's wife!  The castle fell to the French in 1648 at the end of the Thirty Years War, and though damaged, was still mostly intact.  In 1865, lightning caused much of the castle to burn, and some restoration work has been completed to the structure in recent years.  Despite the restoration, it is still a considerable sight and worth a trip, though I remember it from boyhood when my grandfather (Opa) took me there.  Then it was largely in ruins.  These photos were taken in 2005.
