Tricarico Cathedral is a Roman Catholic cathedral church in the city of Tricarico. Robert Guiscard erected the present building in the Romanesque style in the 11th century using a gift from his nephew Robert, Count of Montescaglioso. Louis I, Duke of Anjou was crowned there in 1383. The church has been remodelled and enlarged several times over the centuries, by Bishops Pier Luigi Carafa senior in 1638, Pier Luigi Carafa junior after the plague of 1657 and Antonio del Plato between 1774 and 1777. The work carried out by the latter bishop gave the cathedral its present appearance.
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.
