The first OpenLivingLab Days event (then known as the ENoLL Summer School) was held in Paris in 2010. Since then, every summer, ENoLL organises the annual summit of the worldwide Living Lab community. OpenLivingLab Days is the flagship event of ENoLL and is hosted by a different Living Lab each year. OLLD was hosted in Paris, Barcelona, Helsinki, Manchester, Amsterdam, Istanbul, Montreal, Krakow, Geneva and Thessaloniki. Because of the global pandemic the 2020 and 2021 edition, known as the Digital Living Lab Days, were held digitally. In 2022 the event was back in its physical form in Turn, Italy. The 2023 edition will be held in Barcelona, Spain.
