The Pont Alexandre III is an arch bridge that spans the Seine, connecting the Champs-Élysées quarter and the Invalides and Eiffel Tower quarter, widely regarded as the most ornate, extravagant bridge in Paris. It is classified as a historical monument.
The bridge, with its exuberant Art Nouveau lamps, cherubs, nymphs and winged horses at either end, was built between 1896 and 1900. It is named after Tsar Alexander III, who had concluded the Franco-Russian Alliance in 1892. His son Nicholas II laid the foundation stone in October 1896. The style of the bridge reflects that of the Grand Palais, to which it leads on the right bank.
