Dallet: Oppidum, Allier and Puy de Mur

Dallet can be explored through several specific themes: from the long history of settlement at the Oppidum du Puy du Mur to the Allier and a hike with a stated distance and duration. The Oppidum extends across Dallet and Mezel; other points of interest include the Pont vert de Dallet, the landscape around Puy de Mur and the longer route of the Via Allier. These different landmarks can help you decide what to focus on during your stay: archaeological heritage, a hike with a specified duration, views and nature, or a section of the route along the Allier.

Archaeological heritage between Dallet and Mezel

The Oppidum du Puy du Mur extends across Dallet and Mezel. Its settlement history dates from the Palaeolithic to the Gallo-Roman period. The remains include a protohistoric fortification and a motte-and-bailey castle with a double ditch and corner towers. The time span and architectural features shed light on different aspects of the site: its historical context spans several periods, while the ditches and corner towers describe specific features of the structure.

If history is your main interest when planning your trip, you will find both a broad time frame and specific architectural features here. The history of settlement is not limited to a single period. Dallet and Mezel share a geographical connection to the Oppidum; the place name alone does not mean that the site belongs to only one of the two municipalities.

A hike with a clear time frame

The “De l’Allier au puy de Mur” hiking route starts in Dallet and follows the Allier along the western slope of Puy de Mur. It is a very easy 6 km hike, taking 1 hour and 45 minutes. Its route, distance and duration are all clearly specified. The route is listed in the PDIPR hiking trails plan for the Puy-de-Dôme department.

The duration gives you a fixed point of reference when planning; however, actual route conditions depend on the weather. The connection between the Allier and Puy de Mur shapes the described route: it starts in Dallet and follows the river along the western side of the mountain. If you choose to focus on a hike, you can use this information about the route, duration and stated difficulty level.

Landscape, views and natural areas

In 2007, 325.6 hectares of Puy de Mur above Dallet were designated an “Espace Naturel Sensible d’Initiative Locale” (ENSIL). The landscape offers walkers 360-degree panoramic views, particularly of the Chaîne des Puys/Faille de Limagne, which is a UNESCO World Heritage Site. This part of Dallet is therefore notable both for its designated area and its expansive views.

Dallet also lies within the Val d’Allier–Alagnon Natura 2000 site. Species found there include beavers, otters, European pond turtles and Atlantic salmon. These species are part of the area’s natural heritage, while the panorama from Puy de Mur offers a landscape perspective. Together, these details provide two different points of interest for visitors interested in nature and landscapes.

Bridges and the route of the Via Allier

The Pont vert de Dallet is located in Dallet on the D769A road, upstream from the new bridge at Mur-sur-Allier. It was inaugurated on 30 July 1899. Its exact location and inauguration date give the bridge a specific historical context, distinct from the long history of settlement at the Oppidum.

The Via Allier provides another geographical connection: the section from Pont-du-Château to Vic-le-Comte reaches Dallet by crossing the Allier on a metal bridge and continues through Mur-sur-Allier. The Pont vert de Dallet is a local bridge with a precisely dated inauguration; the Via Allier, by contrast, describes a longer route section between several towns. If you consider Dallet as part of a route, you can distinguish the local significance of the bridge from the wider route of the Via Allier.
