Puntal dels Llops is a small Iberian hilltop fort, located near the modern town of Olocau, in Valencia province. It overlies an earlier Bronze Age site. Its original name in Iberian is unknown. It was built in the late fifth or early fourth century BC and destroyed violently around the end of the Second Punic War or in the early second century BC.
The site is part of a network of fortified sites that surround the large Iberian town of Edeta (Tossal de Sant Miguel, Llíria) and so is important to understanding the formation and organisation of Iberian polities. The archaeological site may currently be visited.
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.
