The Ton Valley defines Martigny; the history of the village can also be explored through a medieval church, historic works of art and well-preserved vernacular civic architecture. This brings together a cultural focus and the valley’s landscape without making them the same travel option.
The Ton Valley and the medieval castle mound
The Martigny area is shaped by the Ton Valley. A medieval castle mound is still visible at the site of the destroyed Château de Martigny. The circular mound is surrounded by a moat and lies on a steep slope above the right bank of the Thon. The mound, moat and hillside setting give the village’s history a spatial dimension: alongside the buildings and works of art, the medieval traces in the landscape offer another way to explore Martigny’s past.
This topographical perspective differs from the history of the Church of Saint-Jean-Baptiste, whose story can be placed in context through specific dates. If you choose Martigny primarily for its historical attractions, you can therefore explore both its architectural and artistic heritage and the location of the castle mound.
Church of Saint-Jean-Baptiste: building history and furnishings
The Church of Saint-Jean-Baptiste in Martigny has been mentioned since 1120. The present building dates from the second half of the 12th century. These dates refer to different periods in the church’s history: 1120 marks the first mention of the church, while the later date refers to the construction of the present building. This distinction helps avoid confusing the historical mention with the construction date of the surviving building.
The furnishings include baptismal fonts made of blue stone. The two side altars contain reused panels, probably originating from the Abbey of Saint-Pierre de Bucilly. The paintings “The Washing of the Feet” and “The Last Supper” also connect Martigny with this abbey: they come from the Abbey of Saint-Pierre-Saint-Paul de Bucilly and were acquired by the municipality of Martigny in 1819. Today, both paintings are protected as movable cultural property.
The church thus brings together several distinct historical aspects: the building’s date, its furnishings of baptismal fonts and reused panels, and the paintings’ origins and later acquisition. If you are interested in sacred architecture, Martigny offers more than a single building period; the artworks and their history add to the story of the building.
Civic architecture and historic stone quarrying
Martigny is one of the canton’s most remarkable municipalities for its well-preserved vernacular civic architecture. This broadens the focus beyond individual religious buildings and artworks to the municipality’s civic architecture. It is a different scale from the history of a single building: here, the architectural heritage of the village as a whole takes centre stage.
Another historical layer is stone quarrying in Martigny, which dates back to the 17th century. Alongside the church and civic architecture, this creates a broader picture of the village: medieval building history, artworks connected with the Abbey of Bucilly and an older history of resource extraction stand as distinct topics. When choosing a culturally focused stay, you can decide whether you are most interested in church art, architecture or the traces of the village’s more distant past.
The Route touristique de la vallée du Ton
The Route touristique de la vallée du Ton is a separate driving option. It runs between Aubenton and Étréaupont along the Ton Valley. For 2026, it is listed as a freely accessible road circuit. The route also recommends visiting the Falaise de Martigny.
Travel planning therefore involves two distinct perspectives: Martigny, with its history of church art and architecture, and the road route along the valley, with its own endpoints. If you are focusing on the village’s history, the church, civic architecture and castle mound provide the main themes. If you are interested in the route, its stated course between Aubenton and Étréaupont is the relevant point of reference.
