La Ruta de la Paz is a sculptural and architectural project realised by Deredia in nine countries along the American Continent. From Canada to the Tierra del Fuego in Argentina, passing through the United States, Mexico, the Yucatan, Costa Rica, Colombia, Peru and Chile, the artist has created a path signposted by monumental sculptural complexes conceived as spaces for meditation. The installations of La Ruta de la Paz are the result of ten years of work and research, investigating and reinterpreting ancient symbolic languages. In order to understand the origins of the project, it is necessary to go back to 1963. Deredia was nine years old when he saw a group of pre-Columbian spheres for the first time in the National Museum of San José, capital of Costa Rica: stone artefacts built by the ancient Boruca Indians about two thousand years ago. Since that moment, he has never stopped asking himself why they were created. Struck deeply by the symbolic value of those mysterious objects, the artist began to study the use and significance given, by other populations of that land, to the spherical element and theme of circularity: a recurrent use of symbology between distant populations even as much as thousands of kilometres apart. From his interest and study, the idea was born of revivifying an ancient symbol shared by millions of women and men over the course of history. The nine structures in the project are characterised by the revival of elements peculiar to various civilisations and of marble spheres aligned with the constellations of each country which in turn host its own monument. In such a way a harmonic whole is created of sites where each single element can emanate the strength and value of the whole.
