The development of Stolberg Castle in its present appearance was essentially proceeded in three phases. In the second half of the 13th century, the original castle (built by the lords of Stalburg in the 12th century) was rebuilt by Wilhelm I of Nesselrode and his son Wilhelm II. After damaged during the Guelders Wars (1502-1543), Hieronymus von Efferen renovated the Stolberg after 1542. A third construction phase was made after 1888 by the manufacturer Moritz Kraus.
Stolberg castle has an late medieval complex on the highest level, with the former guard tower, Palas, two towers, the Renaissance court hall as well as the upper gate, the western tower and the remains of the curtain wall. The second part includes additions of the 19th and 20th centuries, which were built on the second to fourth floors.
Today, Stolberg Castle hosts cultural events and clubs. In the cellar there is a restaurant and a home and crafts museum.
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.
