The idea of integration between art and architecture dates back to the very origin of the discipline, however, it took on a new meaning and social purpose during the Avant-Garde movement of the early twentieth century, becoming one of the most defining characteristics of Modernism. This close relationship is evident in the works of some of the greatest modern architects, such as Mies van der Rohe, Le Corbusier, and Oscar Niemeyer, to name a few.
