The settlement of Titamanninga was first mentioned about 790 AD, then a possession of St Peter's Abbey, Salzburg. After the Archbishops of Salzbug had achieved immediate status in the late 13th century, Tittmoning Castle was built as a border fortress against the incursions by the Dukes of Bavaria. The episcopal administrator of the castle and its environs was called burgrave, as was Ulrich von Wispeck in 1282. Tittmoning was occupied by the forces of the German king Louis the Bavarian during his conflict with the papacy in 1324; nevertheless, he restored it to the Salzburg archbishops three years later.
Temporarily given in pawn to Bavaria, the unlucky Prince-Archbishop Wolf Dietrich Raitenau had to cede the castle to the Bavarian duke Maximilian I in 1611; it was repurchased by his successor Archbishop Mark Sittich von Hohenems and rebuilt as a hunting lodge according to plans designed by Santino Solari. By the 17th century the castle had finally lost its character of a fortress and became the summer residence of the Prince-Archbishops. Upon the Congress of Vienna, the Rupertiwinkel region finally fell to the Kingdom of Bavaria and Tittimoning Castle, damaged by French troops during the Napoleonic Wars, passed under state-ownership.
In the early years of World War II the castle was used as a prisoner-of-war camp for officers, Oflag VII-D. British and American citizens were also interned there. Today Tittmoning castle is a museum.

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.
