The Fonderies covered garden is on Nantes Island, a large ongoing urban planning project since 2000. The garden is set up under a converted 3200 square meter hall, which used to house the Atlantic Foundries, where famous ship propellers were melted.
The whole is covered (by a transparent screen made out of polycarbonate crystal on approximately 60% of the surface, as well as steel roofing), except for a few bays.
The garden itself is organized in two parts:
• on the west side, around the old furnaces, and in the extension of the square, the « furnace garden » takes up the first five bays.
• to the east, taking the remaining eleven bays, the « voyage » garden.
The « furnace garden » is part of the same terrain as the square; it leaves exposed the remains of the old industrial activity, whether it be the furnaces themselves or the vestiges of train tracks, or pits dug into the ground. The idea is not to stage these in a too « museum « way, but to integrate them to this new space.
The theme of the « Voyage » garden is simple: to combine in this neighborhood garden exogenous species arrived in Europe via the Atlantic coast (the ports of Nantes, Bordeaux, Rochefort, le Havre, as well as the further ports of Flandres…); the « travelling plants » were brought back during great expeditions.
The idea was not to design a botanical garden, but to assemble in one place plants that came from far away, many of them having made the transition into our ordinary lives, such as rhododendrons, azaleas, hydrangeas, magnolias, camellias...
Keeping the hall implies the fact that the garden will be covered, despite all the irrigation problems this causes. But the importance of irrigation control lies in the fact the enclosing associated with humidity control allows us to put the plants at their frost resistance limit, giving the garden a singular and exotic expression.
