Over the next five years a competitive and yet collaborative site selection process played out and Lund, Sweden was chosen as the preferred site; the definitive selection of Lund was announced in Brussels on 28 May 2009. On 1 July 2010, the staff and operations of ESS Scandinavia were transferred from Lund University to 'European Spallation Source ESS AB', a limited liability company set up to design, construct and operate the European Spallation Source in Lund. The company's headquarters are situated in central Lund.
