Schloss Weitenburg, Medieval château in Starzach, Germany.

Schloss Weitenburg is a three-winged residential castle on the northern slope of the Neckar valley between Börstingen and Sulzau. Its main building, the Ehingerbau, is a plain three-storey stone house with a huge pitched roof and small dormer windows; a taller cream tower with a crenellated roofline and a rounded turret stands to its right, while a lower wing with a steep reddish-brown roof and a small red-hipped structure complete the ensemble.

The Barons of Rassler acquired the castle in 1720, establishing a family presence that would span generations. Today the ninth generation of the family continues to manage the property, representing an unusual continuity of ownership.

Since 1998, civil weddings have taken place in the Prunkzimmer, the Red Salon, not in a chapel. The castle also gives its name to Golfclub Schloss Weitenburg, whose course laid out in 1984 lies below the castle in the Neckar valley around Sulzau.

The castle operates as a three-star hotel with 25 rooms, serving a daily breakfast buffet in its dining facilities. The on-site restaurant is open Tuesday through Sunday, making it accessible even for day visitors who want to experience the interior.

The castle's main building, the Ehingerbau, was built in 1585 by Jakob von Ehingen, who had no children and sold it to Duke Johann Friedrich of Württemberg. The entrance portal added in 1656 by Quirin von Hönstett carries the initials QVH worked into its cartouche ornament.
