Martigny: Church Art and Medieval Traces

Martigny combines the influence of the Ton Valley with striking examples of architectural and artistic heritage. The Church of Saint-Jean-Baptiste, a visible medieval castle mound and the Route touristique de la vallée du Ton offer different ways to explore the area. If you choose a destination for its historic traces and landscape setting, you will find several distinct aspects here.

Landscape and Medieval Traces

The Ton Valley shapes the area around Martigny. Its architectural history is also part of the town’s character: thanks to its well-preserved vernacular secular architecture, Martigny is one of the canton’s most notable municipalities. Stone quarrying in Martigny dates back to the 17th century. These different themes offer a view beyond individual sights, encompassing the landscape, architecture and the long history of stone quarrying.

A medieval castle mound is still visible at the site of the destroyed Château de Martigny. It is circular, surrounded by a moat and situated on a steep slope above the right bank of the Thon. Its shape, moat and hillside location describe a specific historic landform; the castle mound also remains a visible trace associated with the destroyed Château. Those interested in historic topography will find a different perspective here than in looking at buildings and their furnishings.

Church of Saint-Jean-Baptiste: Architecture 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. The early reference and the construction date of the present building are different historical points of reference: the church is mentioned earlier than the surviving structure was built. The church contains baptismal fonts made of blue stone.

The altars and paintings also tell the story of the church’s furnishings. The two secondary side altars contain reused panelling installed in 1948, probably from the Abbey of Saint-Pierre de Bucilly. The paintings “The Washing of the Feet” and “The Last Supper” come from the Abbey of Saint-Pierre-Saint-Paul de Bucilly; the municipality of Martigny acquired them in 1819. Both paintings are protected movable cultural property. The panelling’s provenance remains a probable attribution, while the origin and acquisition of the paintings are clearly established.

The site’s historical highlights therefore differ: at the castle mound, the focus is on the landform and the site of the destroyed Château; at the church, it is on the construction period and furnishings assembled over the centuries. Martigny offers both a topographical perspective and an art- and architectural-historical one, giving you a choice of focus based on your interests.

The Ton Valley and the Road Route

As a wider point of interest, the Route touristique de la vallée du Ton runs along the Ton Valley between Aubenton and Étréaupont. For 2026, the route is listed as freely accessible and designated as a circular road tour. It also recommends visiting the Falaise de Martigny. This adds a landscape perspective to the area’s history without replacing the municipality’s architectural and artistic heritage.

You can give these themes different weight when planning your trip: the church represents historic building phases, baptismal fonts, altars and paintings; the castle mound represents a medieval landform; and the route is a circular road tour along the Ton Valley. This lets you choose Martigny based above all on the aspect that interests you—church furnishings, visible medieval traces or a route focused on the landscape.
