Competition: Dezeen has teamed up with conservation group the Twentieth Century Society to offer five readers the chance to win a guide to London's Brutalist architecture.
The double-sided foldout map聽features over 50 leading examples of Brutalist architecture, including the National Theatre, the Barbican and Balfron Tower.

Lesser known buildings like the Elephant and Rhinocerous Pavilion at London Zoo, Hyde Park Barracks and Keeling House in Bethnal Green are also amongst the points of interest, along with details for each building including the location, date, the architect and listing status.

"This map is a fantastic opportunity to highlight some of London's boldest and exciting post war buildings," said Henrietta Billings of the Twentieth Century Society. "Ten years ago this style of architecture was completely out of fashion, but now more and more people can see what's great about these buildings."

Alison and Peter Smithson are believed to have been the first architects to adopt聽the term Brutalism ? deriving from the French term for raw concrete b茅ton brut used by Le Corbusier in the late 1940s.

Over the years, the movement has provoked strong reactions and arguments. Recently, a bid to grant listing status to the Brutalist Robin Hood Gardens estate in east London failed and the local MP called for it to be "brought down ASAP".
