Originally designed in the 17th century for Cardinal Richelieu and later converted into the residence of the king, the Palais-Royal has since undergone a number of evolutions, charting alongside the major political developments of France itself. Toward the end of the 18th century, when it had been completed by three majestic wings, its courtyards and gardens became a meeting spot for revolutionaries. At the same time, it became a center of commerce, by day, and vice, by night.
