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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
