Brutalist architecture is a movement in architecture that flourished from the 1950s to the mid-1970s, descending from the modernist architectural movement of the early 20th century. The term originates from the French word for "raw" in the term used by Le Corbusier to describe his choice of material béton brut (raw concrete). British architectural critic Reyner Banham adapted the term into "brutalism" (originally "New Brutalism") to identify the emerging style.
