Founded in 2016 by Luís Castanheira Loureiro and Ana Raquel Ruivo, NO·NO is a contemporary art gallery based in Lisbon, Portugal. The gallery began its activity as ACERVO in the neighbourhood of Madragoa, Lisbon. In 2020 it changed to its current facilities in Estrela, and the gallery changed its name to NO·NO.
NO·NO complements its regular in-house program with national and international programs and collaborations, and with the regular attendance of international art fairs.
