The Monte Sannace Archaeological Park is home to one of the most important indigenous sites of the pre-Roman Peucetian tribe. The settlement has offered up archaeological evidence dating across a vast period stretching from the Iron Age to the early Roman Empire. The site flourished between the 6th and 3rd centuries BC, and in particular during the Hellenistic Age. In the second half of the 4th century BC, Monte Sannace was enclosed with defensive walls that divided the settlement between acropolis and town on the plain to the west. The archaeological value of the site is complemented by its landscape, which offers visitors the opportunity to fully immerse themselves in the Murge.
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.
