Trips Castle was built in the 15th century and has a nearly square shape with a courtyard. The building has a two-story brick structure with a high substructure and an impressive seven-story tower with a capped roof on the western side. The corner towers still have partly intact corbels. The castle was modified in the 18th century, mainly around the courtyard and inside the buildings.
There are two gatehouses dating from the second half of the 17th century that connect to the main house. The inner gatehouse has a main gate in the north wing with a projecting gable. The building beside the gate was converted into living quarters for the tenant. On the south side of the main castle is a geometrically arranged garden with two summer houses from the 18th century.
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.
