This year’s edition of Art Basel in Switzerland has been cancelled, a revision of an earlier decision to postpone the fair usually held in June, until September. Galleries are instead invited to take part in the second edition of Art Basel’s Online Viewing Rooms, launched earlier this year following the cancellation of Art Basel Hong Kong. ‘Unfortunately, too many certainties remain to go ahead with the fair,’ wrote the fair’s organisers in a statement issued on Saturday. ‘These include the health risks posed by large gatherings, the limitations on intercontinental travel, and the unclear Swiss regulatory environment for shows of Art Basel’s size.’
