Pont Alexandre III Paris

Built for the 1900 Exposition Universelle (World’s Fair) to link the Grand Palais and Petit Palais with Les Invalides on the Left Bank, this Beaux Arts–style single-span steel bridge – a listed historical monument – is emblazoned with cherubs and nymphs, with four 17m-high pylons topped with statues of gilded winged horses. From the bridge there are sensational views of the Eiffel Tower. Art nouveau lamps illuminate it at night.
