The third edition of 1+1+1, the exhibition format conceived by Elena Quarestani with Marco Sammicheli, in 2019 returned to investigating the relationship between art, architecture and design through the work of three practitioners. An architect, Andrea Branzi, a textile designer, Chiaki Maki and an artist, Andrea Mastrovito, were all invited to create installations and site-specific works in the evocative spaces of Assab One.
Mastrovito created a site-specific installation for the occasion, "Babel", as well as exhibiting a small version of "The Island of Dr. Mastrovito" on the tenth anniversary of the exhibition “Encyclopedia of Garden Flowers,” which, at Assab One, had given rise to this type of work.
