Culan Old bridge, Stone bridge in Culan, France

Culan Old bridge carries a communal road over the Arnon southeast of the village. It is built of grey and tan rectangular stone blocks with four semicircular arches, the leftmost set slightly lower, and a low parapet of protruding stones along the flat top; a black lamp post stands at its left end. The roadway rises in a slight hump, and the abutments are reinforced upstream and downstream.

The bridge was built in the 17th century on the old road from La Châtre to Montluçon, replacing earlier destroyed bridges whose exact location is uncertain, possibly including a Roman bridge. It was restored in the 19th century and listed as a monument historique by decree on 16 June 1986.

The bridge carries a communal road and is too narrow for two vehicles to pass; heavy vehicles are not allowed to use it. Its name, pont Vieux, distinguishes it from newer crossings, and the nickname "pont romain" recalls the earlier bridges it replaced, possibly including a Roman one.

The bridge is accessible on foot through the local road V.C. 4 de La Garde Dieu and lies near the monument in the village. Visitors should be prepared for uneven ground and wear sturdy shoes, as some pathways around the old structure are not paved.

The bridge is too narrow for two vehicles to pass each other, and heavy vehicles are not allowed to use it. It still carries the local road across the Arnon, on the old route from La Châtre to Montluçon.
