The Jardin des Tuileries is a formal gravel garden between the Louvre and the Place de la Concorde, laid out on one straight line. Stand at the rim of the octagonal basin at the Concorde end and the whole axis is in front of you: the obelisk, the rise of the Champs-Élysées and the Arc de Triomphe two kilometres off. Turn round and the same path runs east through a wood of chestnuts. Loose green chairs sit around the water, and people drag them round to face the sun.
The garden was laid out to frame a palace that no longer exists. Catherine de' Medici began it in 1564 on ground where tile kilns had long worked, and the French word for those kilns, tuileries, became its name. From 1664 André Le Nôtre rebuilt it for Louis XIV around one straight line running east to west, with basins set along the path and raised terraces down both long sides. Paris later carried that line on westward. The palace at the eastern end burned in 1871, and the ruin stood until it was pulled down in 1883.
