The first modern zoo in the world, built in 1793, opened in Paris, France. The menageries of French Aristocrats, including the King and Queen, were taken by the leaders of the French Revolution, and relocated to the Menagerie du Jardin des Plantes. The facility is still a busy and popular zoo in downtown Paris.
