Steinsberg Castle was first mentioned in the year 1109. In the thirteenth century the owners of the castle were the Counts of Oettingen. Later the castle became home to the Counts palatine of the Rhein. In 1517 the castle was purchased by the Lords of Venningen. Shortly after this purchase the castle was burnt down during the Peasants' revolt. The rebellious peasants had to pay 5000 Gulden for the rebuilding of the castle. After heavy damage in 1777 by a strike of lightning the castle was left in disrepair. Since 1973 the castle has been owned by the Sinsheim council, who had large parts of the castle restored. The keep, the moat and the towers may still be viewed today.
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.
