Place de la Concorde, Paris, (where hotel CrillIon stands). At the center, the grand obelisk that Napoleon brought back from his Egyptian campaign. Its twin, known as "Cleopatra's Needle" can be found in New York's Central Park.
The Jardin des Tuileries is one of Paris's most visited gardens thanks to its central location between the Louvre and Place de la Concorde. As such the Tuileries are part of a grand central axis leading from the Louvre all the way to La Défense.
