Last Tuesday, Casa do Design marked the start of the third edition of the Porto Design Biennale with the opening of the exhibition "Petrichor: the Smell of Rain," curated by Fernando Brízio. During a guided tour of the exhibition, the curator developed the central idea of the exhibition, that water shapes everything, in a journey through the six structuring lines of this edition of the Porto Design Biennale, responding to the theme "Being Water: How we flow together and shape each other". The exhibition can be visited until December 3rd. Admission is free.
