Château de Hierges is a partially ruined castle. The castle, originally called Château de Jerusalem (Castle of Jerusalem) was built on the site of a castrum whose origins date back to the 9th century, when the seigneurie of Hierges was part of the property of the house of Ardenne. At the time of the Crusades, the fortress of Hierges was given to the Prince-Bishopric of Liège and, in the 12th century, the castle was destroyed.
The castle was rebuilt in the 16th century, starting in 1560, with more comfort and openings for firearms. In the 18th century the former common and the dovecote were added. The castle was assaulted by revolutionaries in 1792 and destroyed by fire on 18 November 1793.
Of this Meuse-style Renaissance castle, there remain the curtain walls and three large round partially ruined towers, constructed in red brick and blue stone. The fourth covered tower, semi-circular in blue stone from Givet, is inhabited by the current owner.
On the towers, gun emplacements provided for mutual defence by cross fire. Some windows have cross mullions.
The exterior gardens have been restored to present the appearance they would have had during the Renaissance.
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.
