Duke Ulrich built Schorndorf Castle in 1538 on the site of what had probably been an older moated stronghold. It formed part of the state of Württemberg's Schorndorf fortifications and was erected with vast effort and outlay, making it the mightiest town fortress in the whole of the duchy in the 16th century. Today Schorndorf Castle is the seat of the city's district court.
In the castle grounds you can see remains of a former bastion of the town fortifications as well as several sculptures (late 20th century) which are part of the Schorndorf Sculpture Trail.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
