Discover the history beneath your feet from January 21 to March 11, 2026 and from April 15 to July 17, 2026 during guided tours of the new archaeological digs in Martigny.
An excavation site open to the public
Since the end of 2025, the Cantonal Archaeology Office, through its contractor InSitu archéologie SA, has been conducting archaeological investigations in the heart of the ancient Roman settlement of Martigny (Rue d’Octodure 32). As part of this, guided tours of the site are organised to introduce the public to the archaeologists’ working methods, the discoveries made and the ongoing interpretations.
These tours, offered every Wednesday over several months, allow you to return at different stages of the excavation and observe the progress of the research.
Insula 14, near the ancient forum
The site in question is Insula 14, a rectangular urban block characteristic of Roman cities. Although situated in the immediate vicinity of the forum – the administrative, political and religious centre of the ancient city, now buried beneath the football and beach volleyball pitches to the south of the excavation site – this area had never before been the subject of in-depth archaeological investigations.
The excavations have notably revealed, in the south-eastern corner of Insula 14, several phases of a luxurious building, featuring high-quality fittings such as heating systems, marble cladding and wall paintings. These elements are linked to circulation or service areas, such as a courtyard and porticoes.
Long-term occupation
The remains bear witness to a long-term occupation of the neighbourhood. The earliest layers of Roman habitation may date from the first half of the 1st century AD. The site subsequently underwent numerous transformations, before being reused in Late Antiquity and the Early Middle Ages, with reoccupations and burials likely dating from between the 5th and 10th centuries.
