Les Deux Plateaux, more commonly known as the Colonnes de Buren, is a highly controversial art installation created by the French artist Daniel Buren in 1985–1986. It is located in the inner courtyard of the Palais Royal in Paris, France.
As described by the architectural writer Andrew Ayers, "Buren's work takes the form of a conceptual grid imposed on the courtyard, whose intersections are marked by candy-striped black-and-white columns of different heights poking up from the courtyard's floor like sticks of seaside rock. ... In one sense the installation can be read as an exploration of the perception and intellectual projection of space."
