Fernelmont Castle is a fortified farmhouse or château-ferme in Noville-les-Bois in the municipality of Fernelmont. It s a large quadrilateral surrounded by an impressive moat. The only original medieval building left is the imposing arcaded prison, built around the 14th century. It is a massive stone structure with a central arched entrance between two hemispherical protrusions. Its internal layout shows that it was well equipped with latrines, niches, basins embedded in the walls, window seats, two fireplaces and, in particular, an interesting floor covered with small painted terracotta tiles. The rest of the castle is in brick and is from the 16th century, with the exception of the Tuscan gallery, which was added in 1621. Since 1986 it has been given new life by a non-profit organization.
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.
