A glittering glass sphere balanced on a steel pier above the harbour of Genoa, the Biosphere was designed by Renzo Piano as part of the regeneration of the old port for the 2001 G8 summit. The transparent dome, twenty metres in diameter, is suspended just off the dockside and houses a tropical greenhouse, a small slice of equatorial forest set incongruously among the cranes and warehouses of the working port. The structure is supported by a single steel arm that holds the sphere out over the water, with a small bridge giving visitors access from the quay. The transparent skin lets light flood the interior, while the climate inside is held at the steady warmth and humidity needed for the plants and animals to thrive year round. Inside, the visit takes around fifteen to twenty minutes, leading through a dense planting of tropical species, including ferns, orchids, palms and exotic flowers, with a small pool at the centre. A handful of animals share the space, among them turtles, small reptiles and brightly coloured birds, all chosen for their compatibility with the closed environment. The educational programmes attached to the Biosphere focus on biodiversity, the threats faced by tropical forests and the work of the wider Aquarium of Genoa group, which operates the dome along with the adjacent aquarium and the Bigo panoramic lift. The whole port-front complex is treated as a single integrated educational and visitor destination. The Biosphere sits within the Porto Antico, the part of the harbour reconfigured by Renzo Piano in the 1990s and early 2000s, and the pairing of the small futuristic dome with the old stone warehouses and the great curved roof of the aquarium has become an emblem of contemporary Genoa. For visitors with limited time, the dome offers a quick and visually striking add-on to a visit to the aquarium, and the combined ticket usually offered by the operator is the easiest way in, with the Biosphere providing a brief jungle-themed counterpoint to the marine theme of the larger institution next door.
