Brutalist architecture is a style that emerged in the mid-20th century, characterized by its bold, rugged forms and the use of raw concrete. This architectural movement often features large, block-like structures with minimal ornamentation, emphasizing functionality over aesthetics. It was popular for government buildings, schools, and housing projects, reflecting a sense of strength and permanence. The term "Brutalism" comes from the French word "béton brut," meaning "raw concrete." Notable examples include the Boston City Hall and the Unité d'Habitation designed by Le Corbusier. Despite its controversial reputation, Brutalism remains influential in contemporary architecture.
