Gregory and Cyril Chapuisat ( born respectively in 1972 in New York and in 1976 in Bienne, Switzerland) live and work "in situ".  They build complex environmental works, notably taking the form of labyrinths, tunnels, burrows, cavities, mountains or spheres, that the spectator discovers in every position, often in the shade, even in complete darkness. The artists have notably exhibited at the Centre Culturel Suisse of Paris, at the CAN in Neuchâtel, at the FIAC in the Tuileries gardens ( 2009 & 2014) and at LISTE Art Fair Basel (2010). In 2006 and 2009, they took part in ArtBasel in the framework of the SWISS ART AWARDS.
