Science belongs to everyone
LewesScience+Technology+Engineering+Mathematics+Festival
A celebration of experiments, ideas and hands-on discovery for all ages—right in the heart of Lewes.
The Lewes STEM Fair returns on Sunday 15 November. We look forward to welcoming you for a day of free activities and discovery.
A festival for every kind of mind
Big questions,
brilliant answers.
The Lewes STEM Festival brings together local researchers, makers, businesses and families to celebrate the ideas shaping our world. Whether you love the stars, bugs, code, machines—or simply finding out how things work—there’s a place for you here.
This year, the festival is focused on one lively, free STEM Fair—full of people, ideas and activities to discover together.
