Brand new arena
For ONS 2024, we introduced a brand-new arena for Technical Sessions, located right at the heart of Hall 5.
By combining networking opportunities, innovative formats, and a series of new stages, we created a vibrant meeting place for speakers, delegates, and exhibitors alike.
Building on this success, ONS 2026 will once again feature a dynamic arena at the centre of Hall 5 – continuing to inspire connection, collaboration, and innovation.
