The Castle Amerongen was built in 1673 on the site of a previous stronghold that had been burned by the French troops during the invasion of 1672. The current building was designed by the architect Maurits Post as a baroque palace for the owners Godard Adriaan van Reede and his wife Margaretha Turnor. In the main hall a central staircase with painted ceiling was built by Willem van Nimwegen. Other ornaments were added in the early 20th century by P. J. H. Cuypers. The gardens contain historical elements and the walls predate 1673.
Near the entrance bridge dating from 1678 is a wooden clock tower from 1728 that contains the original clock of the same date. In the north-east corner of the gardens is an orangerie dating from the 1880s, and the north wall was raised during the period when Wilhelm II was residing there 1918-1920. He abdicated in Amerongen then moved to Huis Doorn.
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.
