The Villa Romana del Casale is a large and elaborate Roman villa or palace located about 3 km from Piazza Armerina. Excavations have revealed one of the richest, largest, and varied collections of Roman mosaics in the world, for which the site has been designated as a UNESCO World Heritage Site.
The mosaic and opus sectile floors cover some 3,500 sq metres and are almost unique in their excellent state of preservation due to the landslide and floods that covered the remains.
Although less well-known, an extraordinary collection of frescoes covered not only the interior rooms, but also the exterior walls.
The visible remains of the villa were constructed in the first quarter of the 4th century AD on the remains of an older villa rustica, which are the pars dominica, or master’s residence, of a large latifundium or agricultural estate.
The owner's identity has long been discussed and many different hypotheses have been formulated. Some features such as the Tetrarchic military insignia and the probable Tetrarchic date of the mosaics have led scholars to suggest an imperial owner such as Maximian. However, scholars now believe that the villa was the centre of the great estate of a high-level senatorial aristocrat.
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.
