WEEK IN REVIEW 'DOUBT IS BEAUTIFUL': CARSTEN HÖLLER ON HIS STAIRCASE ARTWORK IN VENICE carsten höller unveils the 'doubt staircase' at palazzo diedo, the recently-opened exhibition space of berggruen arts & culture in venice. the spiral, oval, and inclined staircase transforms an originally unfinished 18th-century structure in the palace into a functional artwork that plays with a sense of doubt when stepped on. ‘we always think about doubt and uncertainty as something bad. I’ve been saying since 1999 that doubt is beautiful,’ the belgian artist tells designboom. ‘it’s just a very natural way of being.’ read our conversation in full here, and discover more recent interviews here.
