Daniel Buren (born 25 March 1938 in Boulogne-Billancourt, Hauts-de-Seine) is a French conceptual artist.

The Palais-Royal, originally called the Palais-Cardinal, is a palace and an associated garden located in the 1st arrondissement of Paris. Facing the Place du Palais-Royal, it stands opposite the north wing of the Louvre, and its famous forecourt (cour d'honneur), screened with columns and, since 1986, containing Daniel Buren's site-specific artpiece, Les Deux Plateaux, known as Les Colonnes de Buren.

Les Deux Plateaux, more commonly known as the Colonnes de Buren, is an art installation in the courtyard of the Palais Royal in Paris, France.

It was created by Daniel Buren.

Night or nighttime is the period of time when the sun is below the horizon. This occurs after dusk. The opposite of night is day (or "daytime" to distinguish it from "day" as used for a 24-hour period). The start and end times of night vary based on factors such as season, latitude, longitude and timezone.

At any given time, one side of the planet Earth is bathed in light from the Sun (the daytime) and the other side of the Earth is in the shadow caused by the Earth blocking the light of the sun. This shadow is what we call the darkness of night.
