Built in the late first century BC, the Villa of Naniglio reached its maximum splendour in the third century AD. The main attraction of the villa is a huge, well preserved water reservoir, comprised of a central nave and two lateral aisles.
The Naniglio is an underground structure consisting of a central nave and two side aisles, with a ceiling made of crossed vaults supported on eight square columns arranged in two rows. This structure is so well preserved that it is possible to fully appreciate its characteristics and architectural quality. At the ends of the reservoir, in fact, are two rooms with multi-coloured mosaic floors featuring geometric patterns and walls covered with plaster.
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.
