In fact the creation of the park was not down to a desire to create a green space, but instead to provide an intelligent and useful surface area to meet the needs of the supermarket that would be built beneath.
This though is not immediately obvious. From the outside, the only sign that there is something unusual afoot here is the giant gaping mouth that sucks in hulking delivery trucks. Devoid almost entirely of explanatory visual information, there are nevertheless two no entrance signs which only 'authorised' vehicles have permission to ignore.
Pass through the park gates and you'll find a green space that initially looks much like any other. Trees and plants have a satisfying level of maturity, and lawns seem completely bedded in. Despite being open for less than a month, there are even already a number of desire paths. Look more closely though and you will begin to see a number of more unusual features.
These all may offer clues, but the answers are to be found underground. Since the 1960s there has been a desire in France to place equipment - car parks, stations, shopping centres - literally out of sight. However, although the equipment can be buried underground, the functional aspects - fire escapes, air outlets, electrical equipment, delivery routes - cannot be completely hidden away, and instead need to be dressed up when they sprout on the surface. Here they have become features in a park.
