Open space without borders

The Three Countries Park (light) in the heart of the Euregio

The Three Countries Park, or 3LP for short, is a wonderful part of Europe. In the heart of the Euregio Meuse-Rhine, centred around the cities of Liège, Hasselt, Maastricht and Aachen, it is an area whose beautiful landscape knows no bounds. Will you find the Three Countries Park on a map? No, because the THREE COUNTRIES PARK is the project area and name of a partnership for cross-border cooperation. Thirteen authorities from Belgium, Germany and the Netherlands have teamed up with a view to preserving and sustainably developing this open space and the quality of its landscape. 

What makes the Three Countries Park so special is the diverse landscape with its wealth of water and soils, its countless species of fauna and flora, its expansive vistas and tranquil spots, as well as its cultural and historical treasures, over an area that does not even extend to 5000 km². There is always something to discover here. The park is the ‘communal garden’ both for the four million inhabitants of the Euregio Meuse-Rhine and for the four million tourists and visitors to the region each year.

Future generations should also be able to enjoy the green heart of the Euregio Meuse-Rhine. This is the ambition driving the partners of the Three Countries Park who are concerned with environmental protection, spatial and landscape planning and the natural and cultural heritage in Flanders and Wallonia with Eastern Belgium (B), the region of Aachen (D) and the region of Southern Limburg (NL). In the spirit of the European Landscape Convention, we have been collaborating with many of the parties involved since 2001 on visions, guidelines and projects for a sustainable and shared future of this open space without borders.
