Located at the centre of the Lake Arena is the Tree of Life, which is a monument, a sculpture, an installation, a building and a work of art at the same time. Created and built by Orgoglio Brescia, a consortium of local businesses and 37 metres tall, this wood and steel structure forms part of the metaphor of the Plant Nursery, the concept behind the Italian Pavilion at Milan Expo. The whole pavilion was designed by Marco Balich, who is also its Artistic Director, and whose other talents include producing large-scale events. The Tree of Life is not merely a traditional and religious symbol; it also reaches out to the future, innovation and technology. From the outset, it was conceived as an interactive icon to capture the imagination of visitors and link Expo 2015’s various pavilions together.
