Depriving nearly all of the senses, on  first glance a “tunnel” may act as the antithesis of a garden. Le Passage Végétal seeks to transform this unpopular urban space by filling it with a moving pattern of increasingly stylized horehound — a medicinal plant in use since Antiquity, which is now endangered but still grows on the square at Saint-François. Through abstraction, the project draws our attention to the delicate beauty that can be found in urban vegetation. The  floral motif continues a long tradition of floral ornament which brings together nature and culture. With the urban “garden’s” details adorning its walls, the underpass becomes a desirable indoor-outdoor space; it serves as a pavilion, providing passerbys a cool shelter with dappled light in the heat of summer.
