ENTRE AVRIL ET AOÛT 1945, UN GRAND NOMBRE DE RESCAPES DES CAMPS DE PRISONNIERS, DES CAMPS DE CONCENTRATION, DES CAMPS DE TRAVAIL FORCE, TOUS VICTIMES DU NAZISME, FURENT A LEUR RETOUR ACCUEILLIS DANS LA GARE D’ORSAY, LE PLUS IMPORTANT CENTRE FRANÇAIS DE RAPATRIEMENT.

The place where the Museo d’Orsay is located today was until 1939 a train station, and then a postal center during World War II. As indicated on the sign, at the end of World War II, the place was used as a place where POWs, labor camp inmates and other victims of the Nazis arrived.
Only in 1977 did the place become the famous museum.
