Castle Treis ruins are situated 70 m high on a promontory and is flowed around by the streams Flaumbach and Dünnbach, both coming down from the Hunsrueck. Today’s appearance is dominated by the mighty restored square-tower. Additionally, there are remains of other buildings of the circular wall maintained.
The exact date of the castle's construction is unknown; Treis Castle may have been built as early as in the second half of the 11th century. The first reliable record of Treis Castle dates back to 1121. That year, Emperor Henry V destroyed a castle at Treis, built by Otto I, Count of Salm. In 1148, Treis castle was held by the Count Palatine of the Rhine, Hermann III of Stahleck. In the course of a dispute over the office of Count Palatine between Hermann III and Otto I, Treis Castle came under influence of the diocese of Trier. Ultimately, the Archbishop of Trier, Albero de Montreuil conquered Castle Treis, making it property of the diocese. It appears that during the 12th and 13th century, the castle would have been controlled by the Archdeacon of Karden. In the late 13th century, there is clear evidence for the castle being owned by the Electorate of Trier and thereby being under direct control of the Archbishop.
During the Palatine succession war in 1689, Treis Castle has been destroyed by French troops, and not been rebuilt.

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.
