The Amphitheatre and (Roman) History of Martigny
26 January 2024
During the reign of Emperor Claudius (41-54 AD), Martigny, a small village of the Celtic tribe of the Veragres, was turned into a Roman city. When he became emperor, he conquered Britain. He made the most direct route to Britain accessible, the Great St Bernard Pass, and reorganised the Valais.
The capital was a newly founded city at the foot of the pass. He named it Forum Claudii Augusti, which later became Forum Claudii Valensium, now known as Martigny. It was also one of the two residences of the governor of the Roman province of Alpes Graiae.

The city was built based on the Roman grid system, formed by three series of five insulae, districts for poor inhabitants. Streets separated these residential blocks.
In the centre were the forum, the temple, the basilica, the public baths and other public buildings. The amphitheatre was built in the early 2nd century near the quarry.
The amphitheatre was used until the end of the 4th century. It could accommodate 5000 spectators. The walls have been restored to their former glory.
