Roman Amphitheatre

The Roman amphitheatre of Martigny (part of the Forum d'Octodure archaeological complex) is one of the better-preserved Roman sites in the Swiss Alps. The oval arena dates from the 1st century AD and could seat around 5,000 spectators — a substantial capacity for a garrison town on the edge of the empire. The tiered stone seating is largely intact, and the scale of the structure conveys how seriously the Romans took their presence here.

The site is open to the public and lies on the eastern edge of town, a 15-minute walk from the Fondation Pierre Gianadda. Visiting in the late afternoon, when the stone glows in the alpine light, is recommended. Entry is free; an adjacent small museum covers the archaeology of the Roman-era town.

A story
Martigny was the Roman town of Octodurus, and Julius Caesar mentions it in his Gallic Wars as the site of a battle in 57 BC — the only time a Valais town appears in a classical text. The amphitheatre was built in the 1st century AD to entertain the garrison and civilian population of what was then an important staging post on the Alpine routes to Italy.
