This performance takes place at the Puente de Cal y Canto bridge in Santiago de Chile, constructed during colonial times at the site where an Inka rope bridge had once connected the south and north of Chile. Vicuña invited friends and passersby to join in creating "a living knot" (un nudo vivo), to recover the memory of the sacred Mapocho Valley and its river, now deeply contaminated. This is one of several "performance-knots" of her Quipu Mapocho, conducted between 2016 and 2017.
