The lack of quality urban spaces is one the greatest shortages of Santiago de Chile. With a population of over six million, and despite the sustained economic growth over the last decades, the urban space has not been adequately planned to provide green areas in keeping with the metropolitan scale of the capital. The city had several plans aimed at improving its network of public spaces, and one of them was the construction of a long promenade surrounded by vegetation. The banks of River Mapocho offered an excellent site for a promenade of this kind, but finally they were occupied by highways and communication networks. San Cristóbal Hill, a strip of land detached from the Andes Mountains towards the south and that enters Valle de Santiago, was finally the location chosen. The hills included a metropolitan park, with an old 10-kilometer long canal along the sides. The new promenade follows the course marked by the canal and adds four kilometers to close the perimeter of the hill, dividing the intervention into five stretches that link up with the lower urban fabric and with the Bicentennial Children’s Park, located on the westfacing hillside.
