Ambrussum is a Roman archaeological site in Villetelle. Ambrussum is notable for its museum, staging post on the Via Domitia, bridge Pont Ambroix over the Vidourle and the oppidum (fortified village). Its history of settlement spanned 400 years.
The whole site is still being excavated. A lower settlement prone to flooding was a staging post for travellers on the Via Domitia and provided stabling and accommodation and the full range of repair facilities that were needed by carts and the Imperial postal service. The higher settlement was based on a pre-Roman oppidum which was within a surrounding wall including 21 towers. The Romans re-modelled the oppidum, so there is evidence of a complete range of housing styles from the earliest one room dwellings to sophisticated courtyard houses on the second century AD.
The Roman road, the Via Domitia, ran at the foot of the settlement, leading from it is a paved road with visible with traces of Roman chariot tracks. The Roman bridge was used until the Middle Ages but fell into disrepair, and only one complete arch remains.
The site was first settled in 2,300 BC and the construction started on the oppidum around 300 BC. It was a settlement of Gauls. The Romans conquered the area in 120 BC. The paved road at the heart of the oppidum was laid around 100 BC. The staging post on the Via Domitia and the Pont Ambroix were constructed at around 30 BC. The flow patterns of the river changed around 10 BC, it became more aggressive and flooding became more frequent. The large houses on the south of the oppidum were built in AD 50. The whole oppidum abandoned in AD 100, but parts of the lower settlement were still in use in AD 400, and the Pont Ambroix continued in use through the Middle Ages.
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.
