The first hill fort overlooking the valley of Wolfach was built by Count Rapoto I von Ortenburg around 1120. Due to the power of Ortenburg house there were many conflicts with neihgbor states in the late 12th century and early 13th century. The castle was destroyed in one of these wars in 1192 and subsequently rebuilt. The medieval castle was sacked and almost completely destroyed in Landshut War of Succession in 1504.
The current Ortenburg castle was built in its current form as a renaissance castle in 1562. The interior furnishing of the halls had been first completed in 1800. Therefore, the castle holds interior decoration and art dating back over the course of two centuries. The precious coffered ceiling of the castle chapel is particularly worth noting. The ceiling, which had been made with five different types of wood, is among the most significant renaissance wood ceilings in Germany. Further art treasures included the knights’ hall and the renaissance inner courtyard. Today, the castle is home to the Ortenburg Castle Museum.
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.
