LONDON, ENGLAND - NOVEMBER 18: A general view of the Barbican Centre on November 18, 2016 in London, England. Brutalism is a style of architecture, which was popular between the 1950s and 1970s, and is typically characterised by large forms and exposed concrete or brickwork. In a speech this month British Transport Minister John Hayes described such modernist architecture as 'aesthetically worthless' and called for a 'revolt against the Cult of Ugliness'.
