Viaduct of Anthéor, Railway viaduct in Saint-Raphaël, France

The Viaduct of Anthéor is a railway viaduct on the Marseille–Ventimiglia line in the Anthéor district of Agay, Saint-Raphaël. It crosses the Anthéor stream valley just before its mouth on the Mediterranean with nine masonry arches, is 123 m long and almost 30 m high, and carries two levels of arches with lighter stone trim on the arch rings and piers.

Built between 1860 and 1862 by engineer Charles Bardal, who had already built viaducts at Bandol and La Napoule, the bridge opened in 1863 with the P.L.M. line from Les Arcs to Cagnes-sur-Mer. In September 1943 it withstood eleven bombing raids and was still reported intact on 15 August 1944, until aircraft and a cruiser's shelling brought down two adjacent piers. A temporary structure reopened the line single-track on 25 October 1944.

The hamlet of Anthéor-Plage grew up a few metres south of the viaduct from 1923, and in 1932 it gained a station, Anthéor-Cap-Roux. The bridge and the beach settlement below it are therefore linked by the same railway that the viaduct carries. On 9 October 2014 a plaque was unveiled on pier No. 6 marking the arrival of the United States Army on the beach 70 years earlier.

The viaduct crosses the Anthéor stream valley just before its mouth on the Mediterranean, in the Anthéor district of Agay, Saint-Raphaël. The Corniche d'Or road runs below and beside it, and the Anthéor-Cap-Roux station, opened in 1932, sits a few metres south of the bridge. Trains still use the line, so the structure is seen from outside only.

On 9 October 2014 a plaque was unveiled on pier No. 6, marking the arrival of the United States Army on the beach of Anthéor seventy years earlier, in 1944. The viaduct itself had been bombed that August: aircraft and shelling from a cruiser brought down two adjacent piers, and a temporary structure reopened the line single-track on 25 October.
