Celebrating 200 Years of Wildlife and Wonder

Welcome to ZSL’s 200th anniversary 

This year, we celebrate an extraordinary milestone: 200 years of ZSL. That’s two centuries of pioneering science, global conservation, and inspiring connections between people and wildlife. 

This hub is your home for all our anniversary activity. Explore stories from our past, meet the people who shaped our journey, dive into podcasts and oral histories, enjoy our “Who Were You at the Zoo?” quizzes, and discover the events and moments marking this special year.
 

This isn’t just our celebration - it’s yours too. 

Whether you’ve visited our Zoos, supported our work, or simply grown up using the words and ideas our science-led charity has brought into everyday life - from “Zoo” to “aquarium” to “jumbo” - you’re already part of our story. 
We’ll be sharing new content, events and experiences here throughout the year, so check back often as the celebrations unfold.
