Lilibeo or Lilybaion was originally a Carthaginian city founded around 397 BCE. It became soon a dynamic trade and handicraft centre. In the Hellenistic period it was a multiethnic town where Punic, Greek and Roman people lived together.
After a long siege, it was subdued by the Romans in the first Punic war in 241 BCE. Cicero mentioned Lilibeo in 76-75 BCE as a 'magnificient town'. During the age of Emperor Septimius Severus (193-211 AD) it was the seat of flourishing Christian community.
Vandals led by Genseric devastated Lilibeo in 440. However, it was still one of the most important cities of Sicily in the early Middle Ages. Later Arabs named the city as Marsah Allah, meaning 'the harbor of God'. This is why the city is today called Marsala.
Today you can visit on a Lilibeo Archaeological Park, which exhibits the Insulae with its mosaics, Roman baths, fortifications and findings.
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.
