Biosfera is a glass and steel facility with a surface of 40 sq.
m and a diameter of 20 metres for an overall weight of 60 tons. Designed by Renzo Piano and given to the city by the Messina family, it was realized and located in the area of Porto Antico on the occasion of the G8 of Genoa in 2001.

Since October 2003 it has hosted a complex range of tropical animals and vegetal organisms.
This small but rich botanic garden represents the beauty, complexity and weakness of tropical forests where birds, such as scarlet ibis, reptiles and insects are free to roam around in a world of orchids.
