Aversa Cathedral has been the seat of the Bishop of Aversa from the bishopric's foundation in 1053. The Romanesque cathedral, founded by Normans and dedicated to Saint Paul, has a spectacular ambulatory and an octagonal dome. It has undergone numerous renovations, up to the current Baroque form. The bell tower was built in 1499.
Francesco Solimena's Madonna of the Gonfalone is kept here. The pre-Romanesque sculpture of Saint George and the Dragon is one of the few surviving free-standing sculptures of its date. An outstanding collection of Baroque liturgical silver is kept in the treasury.
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.
