Monuments in Paris: Le pont d'Iena Napoléon I ordered the construction of the Iéna bridge to commemorate his 1806 victory there against the Prussians . It was built between 1808 and 1814, but narrowly escaped being blown up in 1815 when his Empire collapsed. The bridge was enlarged in 1937 because of the increase in traffic and the demands of the Universal Exposition of that year. Le pont de l'Alma : The existing bridge was built in 1970-74 to replace one built by Napoéon III to commemorate his 1854 victory in the Crimea. Only one of the four statues that embellished its predecessor has been preserved. The Pont de l'Alma became world-famous recently because of the tragic death of Princess Diana nearby. Le pont Alexandre III : This bridge is classed as a 'Monument historique,' representative of late XIXth century architecture and decoration. It was built between 1897 and 1900, and inaugurated as the Universal Exposition of 1900 opened. It was completely renovated in 1991.
