Ehrenburg Palace was built by Johann Ernst, Duke of Saxe-Coburg, in 1543-47. It replaced the Veste Coburg as the Dukes' city Residenz. The new city palace was built around a dissolved Franciscan monastery.
According to tradition, the palace was named Ehrenburg ('Palace of Honour') by Emperor Charles V for having been constructed without the use of forced labour.
In 1690, a fire destroyed the northern part of the palace. This was an opportunity for Albert V, Duke of Saxe-Coburg, who had a new Baroque style palace built in 1699.
In the 19th century, Ernst I had the palace redesigned by Karl Friedrich Schinkel in Gothic Revival style, beginning in 1810. Between 1816 and 1840 the state apartments were redesigned in the French Empire style.
The palace is used as a museum today. Among other exhibits, it features art galleries with works by Lucas Cranach the Elder, Dutch and Flemish artists of the 16th and 17th centuries as well as romantic landscape paintings.
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.
