Brutalist buildings and structures can be found throughout the world; you've probably seen many without realizing it. In addition to Le Corbusier's Unité d'Habitation that started it all, his Notre Dame du Haut in Ronchamp, France, is "one of the most important buildings of the 20th century," according to Dezeen.com.
In the U.K., wife and husband team Alison and Peter Smithson "led British Brutalism through the latter half of the 20th century," according to ArchDaily, designing "streets in the sky" modern housing, as well as the headquarters of the Economist and a building at Oxford University.
Swiss-British architect Richard Seifert was prolific in his creation of Brutalist buildings, including the 34-story "'beehive' grid of glass and concrete" Centre Point in London, which was unused for decades and has now been redeveloped into a high-end residential tower. Barbican Centre and Estate is another of London's famed Brutalist structures; its architects at Chamberlin, Powell and Bon were inspired by the Unité d'Habitation.
Another attempt at "reimagining apartment living," Moshe Safdie's Habitat 67, built for the 1967 World's Fair in Montreal, combined the concrete of Brutalism with Japanese Metabolism for a look that is defined by modular cubes.
Boston is home to many examples of Brutalist architecture, including Boston City Hall, which has been described as a "concrete fortress." Its design is the result of an international contest for which the winning concept was submitted by Gerhard Kallmann, Noel McKinnell and Edward Knowles, admirers of Le Corbusier.
One of the most recognizable Brutalist buildings is the Geisel Library at University of California San Diego. Designed by William Pereira, completed in 1970 and constructed of reinforced concrete and glass, the building's two-story pedestal holds six additional stories, cantilevered above it.
