Twentieth Century Society

C20 – The community for modernity. C20 Society is an independent charity and the guardian of Britain’s modern design heritage, campaigning to save the best of twentieth and twenty-first century architecture for future generations. Over the past 40 years we've rescued some of the most beloved local and national landmarks. From iconic red phone boxes to art deco lidos, brutalist carparks to pop-art murals, even helping Bankside power station to become the cathedral of art, Tate Modern. Today, our casework team tackles hundreds of cases of at-risk buildings each year, while our campaigns lead the debate on the built heritage of the future, championing environmental arguments and community solutions. To get involved, you can become a C20 Member or support our vital work via volunteering and donating.
