Stetten Castle was built around 1200, probably on a predecessor site, although there is no architectural evidence of this. At that time, the Knights of Stetten were vassals of the Hohenlohe family during the time of the Staufer dynasty.
The castle was first expanded around the year 1400. To better protect the inner castle against the increasingly common firearms, a moat was dug in front of the outer bailey. At the same time, a curtain wall with semi-circular flanking towers was erected. In the mid-15th century, the corner towers of the curtain wall were added in another construction phase.
In 1488, the Lords of Stetten became involved in a heated dispute with the Lords of Hohenlohe. During the course of this feud, the Hohenlohe forces besieged Castle Stetten and captured the outer bailey. After tough negotiations and the involvement of various mediators, the disputants peacefully reached an agreement, which is why there was no major damage or destruction of the castle.
The last addition was the baroque 'Outer House' in the outer bailey in 1716, which resembles a palace; this is likely why the present place name came into use. The last major structural alteration took place in 1870. At that time, the inner moat was partially filled, and the gatehouse was modified to allow carriages to enter.
Today Stetten castle is used for senior-friendly living.
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.
