The origins of Gesualdo Castle can be traced back to the Middle Ages during the Lombard conquests in southern Italy in the 7th century. It was founded either by the legendary Knight Sessualdo or by Radelchi, Prince of Benevento, as a defensive outpost. The first documented records date back to the 12th century under Norman rule, with William of Altavilla as the first lord. The castle gained importance during the Norman-Swabian era and became a prominent fortress in the region.
Carlo Gesualdo, a descendant of the Norman line, transformed the castle into a Renaissance-style mansion in the late 15th century. Over the centuries, the castle suffered damage and looting during various conflicts, including the Franco-Spanish War and the arrival of French troops in 1799. It underwent significant renovations in the 19th century and was designated as a site of historical and artistic value in 1913. The castle was severely damaged in the 1980 Irpinia earthquake and has undergone ongoing restoration efforts. Currently, a portion of the castle is open to the public, and future plans include establishing a polyphony education high school within its premises.
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.
