Lübeck Town Hall is one of the most beautiful town halls in Germany. From 1230, three gabled houses were constructed on the marketplace and extended over the next few centuries to ultimately create the Hansesaal (Hanseatic Hall) for meetings; and the Danzelhus (Dance Hall) for social meetings.
Its interior boasts a grand audience hall: Don't be surprised to see the doors to this former courtroom have different heights. Acquitted defendants were allowed to leave the hall via the tall door, sentenced defendants had to remove their hats and leave via the low door.
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.
