Yes it's a map and yes people are walking on it! Why? Because it's meant to be that way! To commemorate the 100th anniversary of WWI, the Senate - withe the help of map maker Michelin - put a giant map in the Luxembourg gardens on which it is possible to see the major battles that took place in the North-East of France. Very clever idea, even on a rainy day like yesterday! On the Luxembourg grids that surround the gardens, you can also see photos that were taken on the battle fields by photographer Michael St Maur Sheil. More (in English and in French).
