Tours & Visits

The European Spallation Source welcomes visitors! ESS is an inspiring project, not only for those who work here but also for the surrounding community and various external stakeholders. In 2018, ESS welcomed 5799 visitors on site in 1079 groups, and similar numbers are expected in the coming years.

The purpose and motivation behind visits to ESS vary: the majority of business visitors directly contribute in order to deliver the project on time and on budget, whereas high-level visiting groups, heads of states, politicians and diplomats visit ESS to experience the international collaboration needed to construct one of the largest science and technology infrastructure projects being built today. With a continued commitment to educational and outreach activities, ESS also receives target groups with various backgrounds to experience the ESS construction site. 

If you are interested in visiting the European Spallation Source, a request must be made, by first creating an account and then filling in the appropriate form. If you have questions, email us at visits@esss.se, but keep in mind that we only accept visit requests through the electronic Visits Request Form.

Please contact us with ample time to plan your visit (30 days in advance is preferred, some exceptions may apply). We will evaluate your request and get back to you within seven days. We are only able to offer group visits. Please note that ESS is limited as to the number of visits that can be permitted onto the construction site, so as not to interfere with the construction work.
