The Swabian Castle in Oria is a wonderful construction built between 1225 and 1233 at the behest of Holy Roman Emperor Frederick II. Over the centuries, it has been inhabited by princes, knights and noblemen. It has a triangular plan and is characterised by three towers called Quadrata (Square), Del cavaliere (of the knight) and Del Salto (Jump): the first one was built during the time of Frederick II, while the other two under the Angevin domination.
According to a local tradition, the foggy atmosphere which shrouds the castle is not just a natural phenomenon, but it recalls something which happened during the construction of the castle, known as Oria Fumosa, foggy Oria. A must-see is the castle at sunset, with an amazing picture-postcard view, which can be admired from any place in the town.
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.
