It was created by Lucas Grandin in 2010 and is made of a wooden structure built on three floors that serves as a panoramic viewpoint on the Wouri River, as a botanical garden and as a dewdrop percussion organ.

In February 2010, Lucas Grandin started working at his Jardin Sonore, a wooden structure built on three floors that serves as a panoramic viewpoint on the Wouri River, as a botanical garden and as a dewdrop percussion organ.

Lucas Grandin's work aroused the passionate interest of the inhabitants of the district, creating a place for socializing and contemplation and covering the urban cacophony inside its water walls.

During SUD 2010, the artist engaged the inhabitants of Bonamouti in the production process of the work though preparatory meetings, the requalification of the area (used before as dumpster on the edge of the river), and the building structure.

The water is collected by the rainfall, stocked in barrels and offered to the vertical garden through transparent tubes using a hydroponic dripping system.
