Kirchberg Castle was initially built around 1240. The first documented mention in 1265 refers to Raben von Kirchberg. The complex was expanded until 1400. Ludwig Kasimir von Hohenlohe bought the castle back in 1562. Under Kasimir and his sons, extensive changes took place: between 1590 and 1597, the medieval castle was transformed into a Renaissance palace. From this period date the hall building, erected on the site of the first castle, two cross buildings, and connecting passages, creating a four-wing complex with bastions facing the town.
Leopoldo Retti planned the conversion into a residence palace under Count and later Prince Karl August of Hohenlohe-Kirchberg, which took place from 1738 to 1745.
The building complex now includes a café, a hotel with conference rooms, and artist studios.
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.
