Schloss Münster, the former residence of the prince-bishop with its rich figural ornamentation of the facades, was constructed from 1767 to 1787 as a three-winged complex by Johann Conrad Schaun. After the war, the exterior aspect was reconstructed true to the original. The castle is built from the typical Baumberger sandstone of Münster.
Today, the palace is used by the university administration. On the Schlossplatz in front of the palace, the great annual funfair - the Send -takes place thrice a year, attracting thousands of visitors. Right at the Schlossplatz, there is also the central lecture hall building of the university, which is frequently used for conventions and even concerts.
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.
