Forty years after the massacre, on 17 October 2001, Bertrand Delanoë, the Socialist Mayor of Paris, put up a plaque in remembrance of the massacre on the Pont Saint-Michel. How many demonstrators were killed is still unclear. In the absence of official estimates, the plaque commemorating the massacre reads, "In memory of the many Algerians killed during the bloody repression of the peaceful demonstration of 17 October 1961". On 18 February 2007 (the day after Papon's death) calls were made for a Paris Métro station under construction in Gennevilliers to be named "17 Octobre 1961" in commemoration of the massacre.
