The Chiostro del Paradiso ('Cloister of Paradise') was built by Filippo Augustariccio between 1266 and 1268 and was used as a burial ground for noble families of Amalfi. The white columns and pointed arches reflect the clear influence that the Arab world had on Amalfi, similar to those found in the courts of the palaces of the Middle East. It is a true open-air museum, with Roman and medieval pillars, sarcophagi depicting the wedding of Peleus and Thetis, the other the rape of Proserpina, a fourteenth-century sarcophagus and fragments of the façade of the Duomo.
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.
