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.

The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
