Located close to the Palacio de la Moneda in Santiago, on Plaza Bulnes, this inflatable structure was the setting of the ceremony that kicked off the 23rd Chile Biennial of Architecture and Urbanism, which took place from 14 to 22 January 2023 and addressed the theme 'Vulnerable Habitats.'

The 30-meter-long, 20-meter-wide silvery bag-like object was inflated by eight pumps, rising to a height of 6 meters to fit in a temporary auditorium good for 250 people.
