Slot Zuylen (Zuylen Castle) was originally built in the 13th century by lord van Suilen en Anholt as a simple donjon (tower). In 1422 during the Hook and Cod wars the castle was completely demolished. In 1510 rebuilding started. In 1752 the castle was modified nto a country mansion. It holds a tapestry by the Delft carpet weaver Maximiliaan van der Gught. Its past inhabitants include Steven van der Hagen and Belle van Zuylen. Slot Zuylen opened its doors to visitors 60 years ago and has meanwhile acquired museum status.
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.
