In 1686, Louis XIV decided the time had come to design a magnificent square, at the center of which would stand a statue of His Royal Highness. Though the statue is long gone, this is still one of the classiest squares in the city. The work of Jules Hardouin-Mansart, this über-elegant octagonal ensemble of 17th-century buildings today is the home of the original Ritz Hôtel, as well as the world’s most glitzy jewelry makers. When Napoléon took over, he erected a huge Roman-style column honoring his glorious army (yes, once again), this time documenting its victory at Austerlitz. A long spiral of bas-reliefs recounting the campaign of 1805 march up the Colonne de la Grande Armée, which is crowned by a statue of the Emperor himself.
