Arc de Campanus

The Arc de Campanus is a well-preserved Roman arch in Aix-les-Bains, likely erected in the 2nd century AD by Lucius Pompeius Campanus in honor of his family. It carries fifteen Latin inscriptions, making it one of the most epigraphically rich Gallo-Roman monuments in the region. The arch once stood between a Temple of Diana and the town's largest thermal baths, suggesting a prominent position along the civic axis of the ancient settlement. Its precise function — honorary monument, funerary marker, or ritual gateway — remains unresolved among archaeologists. Classified as a French historic monument, it stands openly accessible within the modern townscape, a compact but genuinely ancient remnant for visitors interested in Roman archaeology.
