La Barre Monument, Memorial monument near railway station in Abbeville, France.

La Barre Monument is a commemorative site in Abbeville near the railway station and the aqueduct spanning the Somme River. It consists of a tapered stone column bearing a bronze plaque with inscriptions about the emancipation of human thought.

In 1902 two teachers and two students of the Abbeville lycée founded the Groupe La Barre and laid a bouquet at the execution site, which the municipality removed. The monument was unveiled on 7 July 1907 before 15,000 supporters who came by train, funded by a lottery of 100,000 tickets at 25 centimes. During the First World War the bronze relief was removed for melting, but a railway worker hid it in a stream and it was recovered after the war.

The monument commemorates a figure persecuted by French authorities and attracts visitors interested in the history of intellectual freedom. The site is regularly visited by secularists and freethinkers who gather here to express their values about free thought.

The monument is located at an easily accessible spot near the railway station within walking distance of the town center. Visitors can explore the site freely at any time, though it is particularly busy during commemorative ceremonies held several times yearly.

The bronze relief panel on the front was removed under Vichy for its metal and loaded onto a train to be melted down; a railway worker hid it in a stream, and it was recovered and put back after the war. The low surrounding grille was removed in the last restoration.
