A British landmark is celebrating a quarter-century of operation by reflecting on its transformative journey from a derelict clay pit to a world-renowned environmental destination.
While the anniversary festivities began with a massive musical tribute in Cornwall, UK, the milestone also serves as a launchpad for a new era of international expansion and record-breaking economic influence.
The celebrations on 17 March 2026 commenced with a 300-strong dawn chorus featuring singers from 16 different community groups across Cornwall. This performance included a specially written song created by Eden staff past and present, concluding with a rendition of “Cornwall My Home” alongside folk musician Harry Glasson. To mark the occasion, a five-tier birthday cake by artist Emily Hankins was presented to co-founder Sir Tim Smit KBE and chief executive Andy Jasper.
A legacy of economic transformation
Beyond the festivities, the landmark anniversary coincides with the release of a significant Impact Report. The findings highlight the “Eden Effect,” revealing that the charity has generated £6.8 billion in total economic impact for the South West since opening in 2001. Over the past 25 years, the attraction has welcomed more than 25 million visitors and supported an average of 700 jobs annually.
“Eden has always been a people story and the support we’ve had from so many institutions, organisations, individuals, communities and volunteers who backed this wild dream – gives me goosebumps even now,” said Sir Tim Smit KBE. “The world today feels a more dangerous place than 25 years ago, and our duty is to commit to spreading the message of possibility far and wide.”
The report also underscores Eden’s educational reach, with over one million schoolchildren having participated in nature-based learning at the site. This data was recently presented to Westminster by CEO Andy Jasper to demonstrate how nature-led regeneration serves as vital economic infrastructure.
Expanding the global footprint
The anniversary marks a pivotal moment for the “Eden Effect” as the model expands across the UK and overseas. Developments are currently underway for Eden Project Morecambe and Eden Project Scotland, following the 2025 opening of Oriental Eden in Qingdao, China.
The organisation’s commitment to innovation remains central to its future. In 2023, Eden made history with the UK’s first operational deep geothermal well since 1986, which now heats the Biomes and onsite buildings. This focus on sustainability is paired with a robust cultural program; in 2026, the venue will celebrate its 150th Eden Session with its largest lineup of live music to date.
Looking ahead to 2026
The 2026 program introduces several new experiences designed to deepen visitors’ connection to the environment. This includes the launch of the Giant Marble Runs on 28 March and a new Japanese tree exhibit.
“Marking 25 years is a proud moment to celebrate everything we have done, but it is also a moment to look forward,” Andy Jasper explained. “Eden was created to show the power of optimism and collective action. We’re more determined than ever with new, exciting projects yet to come!”
Amid the celebrations, the organisation also paused to honour Sir Ronnie Hampel, Eden’s early Chairman, and Sir Nicholas Grimshaw, the visionary architect behind the iconic Biomes, both of whom were instrumental in the project’s inception.
