Trimburg is a hilltop castle in Lower Franconia, built by Gozzwin of Trimberg in 1135. Originally the castle was formed by three different sub-structures that came from different periods of time. The ruins preserved today are from the last time period.
The oldest part of the castle was named Leuchtenburg or Alte Burg. During the Peasant's War in 1525 the castle was captured and destroyed. Also during the Thirty Years' War, the castle suffered a new destruction. Afterwards the castle Trimburg was rebuilt from scratch with a new architectonical character of a palace.Through the fact that the surrounding country was in neediness of stones, it was partly deconstructed and the building material was used for building new houses in the towns.
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.
