The Kammerzell House is one of the most famous buildings of Strasbourg and one of the most ornate and well preserved medieval civil housing buildings in late Gothic architecture in the areas formerly belonging to the Holy Roman Empire.
Built in 1427 but twice transformed in 1467 and 1589, the building as it is now historically belongs to the German Renaissance but is stylistically still attached to the Rhineland black and white timber-framed style of civil (as opposed to administrative, clerical or noble) architecture.
It is situated on the Place de la Cathédrale, north-west of the Strasbourg Cathedral, with whose rosy colour it contrasts in a picturesque way when seen from the opposite direction.
The building's inside has been decorated on all floors by lavish frescoes by Alsatian painter Léo Schnug (1878-1933). It now houses a restaurant.
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.
