“Il Corridoio Rosso" is a tale of two corridors, one a copy of the other. One corridor is that of the installation curated by Giovanni Agosti and Jacopo Stoppa at the Triennale di Milano for the 23rd International Exhibition "Unknown Unknowns": the visitor crosses it to access four mysterious rooms inspired by natural elements. The other corridor is that of Agosti's own home, a place saturated with books, paintings and objects that contains - conceals - clues, traces and memories of a lifetime. Fiction and reality blur in a dual exploration that leaves unresolved the mystery of what is hidden at the end of the corridor.
