The Tree of Life is the symbol of the Italian Pavilion, a place for entertainment and a global icon. It represents the importance of embedding roots into the past and traditions in order to open up to a future full of culture, innovation and fruitful collaboration among the various populations.
The structure, designed by the creative director Marco Balich, buds from the search for a decidedly Italian symbol, representative of one of the most extraordinary periods of human genius: the Renaissance period. The architecture of the Tree, which technically represents an “extrusion” from Michelangelo’s floor in the Piazza del Campidoglio, reaches a height of 35 metres and its foliage widens out to about 42 metres.
