Rabenstein Castle is a former high medieval aristocratic castle in the municipality of Ahorntal in the Upper Franconian county of Bayreuth. The spur castle may be visited for an entrance fee.
In the vicinity of Rabenstein Castle there used to be several other castles: on the opposite side of the valley is the suspected site or burgstall of Brunnloch or Rabenloch, a little further up the Ailsbach valley once stood the castle of Ahorn, the present day hamlet of Klausstein, opposite it is probably the site of Hohenloch Castle above Ludwig's Cave, down the valley lies the Alte Veste and in the village of Oberailsfeld there was once another small fortification, Ailsfeld Castle on a rock in the valley. Towards the west, above the valley of the Wiesent, stands Rabeneck Castle, a fortification probably founded by the Rabensteins.
The oldest parts of the castle were built in the first quarter of the 12th century as a residence in the Barony of Waischenfeld. At the same time the ministerialis family of Rabenstein, who were the builders of the castle and bore the raven on their coat of arms, were recorded as being in the service of the barons of Waischenfeld. In the early 13th century, the outer ward was expanded. During the following centuries ownership and occupancy of the castle changed hands several times. Its occupants included the House of Schlüsselberg and its lords, the burgraves of Nuremberg. In 1450 the castle was destroyed in the First Margrave War and in 1489 was rebuilt by Conz of Wirsberg.
In 1557 the castle went to the von Rabensteins who had ambitions for the nobility and bought back their family seat. Daniel of Rabenstein remodelled the castle in 1570, the old outer ward being merged with the inner ward.
During the Thirty Years' War, the castle was again completely destroyed by imperial troops, because its lord, Hans Christoph of Rabenstein, aligned himself with the Swedes. After the war between 1648 and 1728 a few small buildings and a farm were re-established.
In 1742 the von Rabensteins died out and the castle went to the counts of Schönborn-Wiesentheid, who revamped the ruins in 1829/30 for a royal visit by Ludwig I.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
