Like most of the castles in the Rhineland-Palatinate, Landeck Castle was built in approximately 1200. It served probably the function of protecting the nearby Klingenmünster monastery. The first documental reference to Landeck Castle was made in 1237.
In the period around 1500 there were castle administrators from the Kurpfalz, the bishop of Speyer and the counts of Zweibrücken. At the end of the 15th century extensive work was done at Landeck Castle. During the Peasants’ War in 1525 it was damaged, but obviously quickly repaired.
In 1570 there was again a change in ownership. After the dying out of the Zweibrücken-Bitch lineage their share of the castle went to the Kurpfalz. It was not until 1709 that the Electors succeded in owning the entire property of Landeck Castle, when the Speyer bishopric gave up the remaining quarter by exchange. The Kurpfalz remained the only owner until the French Revolution. In the 1960’s the castle was extensively restored.
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.
