The present 62-metre-long bridge dates to 1857, requiring only seven months for construction, from the date the older bridge was closed to traffic, and was designed on three 17.2m arches by Paul-Martin Gallocher de Lagalisserie and Paul Vaudrey. It was the site of many of the killings of protesters by the police, in the Paris massacre of 1961, and a commemoration plaque on the bridge was unveiled by the mayor of Paris in 2001.
