Grzegorz Kowalski’s sculpture “Reloj Solar," Mexico City. ’68 Olympics Organizers commissioned a series of 22 public artworks from around the world for the Ruta de la Amistad (Road of Friendship). The statues lined ten miles of road in a barren area south of the city, near the newly constructed Olympic village. Mexico City has tripled in size since 1968 and these statues are now in the one of the most densely populated areas of the city. The tiny road has become a major multi-level highway, the Periferico Sur. An effort is underway to restore the statues and relocate them to dedicated sculpture parks nearby. Photo by Gary Hustwit.
