Pont au Change

The Pont au Change is a bridge over the Seine River in Paris, France. The bridge is located at the border between the first and fourth arrondissements. It connects the Île de la Cité from the Palais de Justice and the Conciergerie, to the Right Bank, at the Place du Châtelet.
Several bridges bearing the name Pont au Change have stood on this site. It owes its name to the goldsmiths and money changers who had installed their shops on an earlier version of the bridge in the 12th century. The current bridge was constructed from 1858 to 1860, during the reign of Napoleon III, and bears his imperial insignia.
