With the support of Leader and Interreg funds, garden festivals were organised in the region of the Our Nature Park in 2000, 2004 and 2007 for which small artist gardens were created in various places. These gardens were planned in close cooperation with the municipalities and are also maintained by them. The gardens show different ideas for the design of public places. For example, a large part of the gardens in the Troisvierges park were created as part of this project.
