Ruderi del ponte romano di Saint-Vincent

A single stone abutment survives from the Roman bridge over the Cillian stream near Saint-Vincent. The central arch collapsed in 1839, but the squared masonry still shows the construction of a crossing on the Roman road toward Gaul.

Why it matters

The bridge formed part of the network of crossings on the Via delle Gallie, the Roman road linking the Po Valley with Aosta and the Alpine passes. Its ruin preserves an unusual view of a bridge's structure: the abutment, stone facing and relationship to the stream remain legible even though the arch is gone.

What to notice

The surviving left abutment is faced with small, squared stones laid in regular courses. The missing central arch exposes the structure's section and the span's former relationship to the Cillian stream.

Context and history

The Via delle Gallie was begun under Augustus and connected Milan, Ivrea and Aosta before dividing toward the Great and Little St Bernard passes. In the Saint-Vincent area, masonry bridges carried the road across tributary streams. The bridge over the Cillian served traffic into the medieval period; its central arch collapsed in 1839 and was not rebuilt.
