The Casa de Campo is one of the largest public parks in the world, a real forest. In the images, its 2019: the green of the earth shining anew for us or the children's unexpected use of bridges and ponds. In the sounds, its 1936, the forest torn in two, the defence of Madrid: "buzzes and explosions, clattering of machine guns, dry crackling of rifles" or the words of those who invented a revolution and a taste for good life in the midst of that turmoil.
