Pont Vieux, Medieval bridge in Millau, France.

Pont Vieux crosses the Tarn River using multiple medieval stone arches and thick masonry walls that connect two parts of Millau. The structure displays several arches of varying sizes, showing the sturdy construction methods of earlier centuries.

A flood of the Tarn destroyed the bridge in 1758; the sources record no rebuilding, only what survived. The remaining structure has been classified as a monument historique since 23 January 1934. It stands on the Tarn in Millau, Aveyron, near the Pont Lerouge.

The bridge defines Millau's streetscape with its heavy stone arches that have shaped the city's appearance for centuries. It shows how medieval architecture runs through daily life and continues to define the character of both riverbanks.

The bridge is easily reached on foot from the city center, where multiple access points are available. The immediate surroundings offer shops and eating places to explore while visiting.

The bridge is classified as a monument historique, a status granted on 23 January 1934, which protects what survives of the structure after the Tarn flood of 1758. It stands close to the Pont Lerouge, another crossing of the river in Millau.
