TIL that the "brut" in Brutalism comes not from the word "brutal", but from the French word "Béton brut" which means "raw concrete". The term is used to describe concrete that is left unfinished after being cast, displaying the patterns and seams imprinted on it by the formwork.
Brutalist architecture is dictated by function over form with raw construction materials and mundane functions left exposed. Reinforced concrete is the most commonly recognized building material of Brutalist architecture but other materials such as brick, glass, steel, and rough-hewn stone may also be used.
The Geisel Library, one of the most famous Brutalist buildings in the world, was financed by a donation from none other than Theodore Seuss Geisel, better known as "Dr. Suess".
