With its varied façades, the Old City Hall, which was built in 1422 as a merchants’ and excise building, is the jewel of Esslingen. The south face is adorned with ”Allemanisch” timber-framing, while the northern face was extensively modernized during the renaissance, and since then has sported a small, two-story clock tower. Inside the clock tower is a glockenspiel, which was donated by the citizens of Esslingen in 1926 on the occasion of the building’s renovation. The glockenspiel has a repertoire of 200 tunes, which can be heard at various times throughout the day. The preserved original clock mechanism from the astronomical clock of 1591 is among the oldest in Germany. The wings of an eagle, the heraldic emblem of the former imperial city, beat in accordance with the striking of the hour.
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.
