Ambianum - A settlement in Belgica also known as Samarobriva
Ambianum was originally known as Samarobriva ("Somme bridge"), the central settlement of the Ambiani tribe, one of the principal tribes of Gaul, who were issuing coinage, probably from Amiens, in the 1st century BC.

It was a large town which controlled the passage of the Via Agrippa connecting Lyon to Boulogne-sur-Mer. The Ambiani derived their name from the Gaulish word ambe, meaning river – a reference to the Somme that flows through Amiens.

The town was given the name Ambianum by the Romans, meaning settlement of the Ambiani people. During the late Roman Empire, the walled city was one of the main rear Roman bases facing the Barbarian Invasions. After Nero's death, it was a centre of equipment of Britannia and saw a flow of legionaries and merchants.
