The Romito cave (Italian: Grotta del Romito) is a natural limestone cave in the Lao Valley of Pollino National Park, near the town of Papasidero. Stratigraphic record of the first excavation confirmed prolonged paleo-human occupation during the Upper Paleolithic since 17,000 years ago and the Neolithic since 6,400 years ago. A single, but exquisite piece of Upper Paleolithic parietal rock engraving was documented. Several burial sites of varying age were initially discovered. Irregularly recurring sessions have led to additional finds, which suggests future excavation work. Notable is the amount of accumulated data that has revealed deeper understanding of prehistoric daily life, the remarkable quality of the rock carvings and the burial named Romito 2, who exhibits features of pathological skeletal conditions (dwarfism).
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.
