Brutalist architecture (also known as Brutalism) is a style of architecture born in the 1950s in the UK. It is often typified by raw concrete constructions and simple, block-like designs. Although the architectural style gained footing in the 1950s during the post-war reconstruction era, Brutalism is considered to be heavily based off of modernist architecture of the early 1920s.
Brutalist buildings often feature minimalist designs that prioritize the structural elements and raw building materials over decorative allure. Classic examples of brutalist architecture include the Boston City Hall in Massachusetts, the Royal National Theatre in London, and the Hayward Gallery on the South Bank in London.
