Brutalist architecture is eye-catching and divides people at the same time – beautiful or terrible? – that’s usually the question.

The “Brutalist London Map” gives an overview of 50 of these concrete giants, including the Trellick Tower, the Barbican and the National Theatre. The map invites us to take a tour of the British capital’s brutalist beauties. It was compiled by conservator Henrietta Billings. She accompanies us on a city walk to meet residents, passers-by and Brutalism fans – and hear their views on this unique architectural style.
