Entremont is a 3.5-hectare archaeological site three kilometres from Aix-en-Provence at the extreme south of the Puyricard plateau. In antiquity, the oppidum at Entremont was the capital of the Celtic-Ligurian confederation of Salyes. It was settled between 180 and 170 BCE, somewhat later than the inhabitation of other oppida, such as Saint-Blaise (7th to 2nd centuries BCE). The site was abandoned when it was taken by the Romans in 123 BCE and replaced by Aquae Sextiae (modern Aix-en-Provence), a new Roman city founded at the foot of the plateau. By 90 BCE, the former oppidum was completely uninhabited.
The site contains two distinct areas of settlement surrounded by ramparts. Archaeologist Fernand Benoit named the older area, on the summit, 'Ville Haute', and the lower 'Ville Basse'. Subsequently it was recognised that the latter was an enlargement of the former, and they are now labelled 'Habitat 1' and 'Habitat 2', respectively.
Finds from the site are displayed at Musée Granet and include statues, bas-reliefs and impressive severed heads.
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.
