On 11 September 2001, the Spanish artist based in New York Elena del Rivero, was in Madrid preparing her forthcoming inauguration when she saw the Twin Towers collapse on the television. While she watched the clouds of dust, she imagined that her studio (located in 125, Cedar Street, just opposite the South Tower) had been destroyed and she also collapsed. She flew to New York and went directly to her creative space but the police wouldn’t let her through that day. Nor the next days, either. Sometime later, the residents of Ground Zero were allowed to return to their homes. Her studio was covered in dust and papers. She cleaned the dust and contamination produced by the attack from all the objects, and then she used a video camera to document the cleaning of the area and its everyday life. She recorded more than 100 hours of footage and she gathered together some 3,000 papers that she numbered, catalogued, photographed and sewed together with silk and pearls.
