Hohenburg castle is assumed to be constructed in the second half of the 13th century. The influence of the Hohenburg family was extensive in the area between Bitche, Saargmünd and Pirmasens. There were feudal relations with the King but also to the Count of Zweibrücken and to the Counts Palatine. The castle is situated close to the German-French border on the Alsace side.
The first known representative of a Hohenburg family was Gottfried Puller who served in the military under the Emperor Friedrich II in 1236. In 1262 the name Hohenburg is documented for the first time, when Konrad and Heinrich of Hohenburg transferred their property to the bishop Heinrich II of Speyer.
The castle was seriously damaged in 1386 by the troops of Strasbourg during the siege and conquest of the neighbouring Löwenstein Castle. During the 30 Year War the castle was seriously damaged and in the 1780’s it was completely destroyed by French troops.
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.
