From 2 to 4 June 2023, Luxembourg is once again participating in the Rendez-vous aux jardins, launched in 2018 by HEREIN, a European network for information and cooperation on cultural heritage which brings together European public administrations responsible for national policies and strategies in the cultural heritage sector. In 2022, some 3,000 gardens in 25 European countries took part in this event, attracting some 2 million visitors. Some 39 private and public gardens took part in the Luxembourg program.
