Raymontpierre Castle is situated on a spur on the north slope of Mont Raimeux. The castle was built around 1594-1596 by Georges Hugué de Raymontpierre, the châtelain of Delémont. His father had received the land as a fief from the Bishop of Basel in 1576. Between 1623 and 1809 it was owned by the Staal family, a noble family from Solothurn. The fortified mansion was eventually converted into a farmhouse. The Buehrle family bought it in 1941 and restored it in 1949.
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.
