The new, interdisciplinary Cambridge Festival (which replaced the Cambridge Science Festival and the Cambridge Festival of Ideas) took place from 26 March – 4 April 2021, primarily online. The new Festival included a uniquely Cambridge eclectic mixture of over 350 events and activities: from panel discussions, film premieres, and guided walking tours, to ‘try this at home’ activities for the whole family. Topics cover the breadth of Cambridge research and were presented across the Festival’s four themes: Society, Health, Environment and Explore!
