The aim of the new circulation system at the Castello di Rivoli and the redesign
of the southeast flank of the adjoining hillside is to create a closer link
between the city and the castle. Rivoli, a small town on the western edge of
Turin, is dominated by this monumental eighteenth-century Juvarra building,
which was never completed. The castle, the culmination of a 13-kilometer-long
baroque axis heading from the city to the countryside, sits atop a moraine.
Castello di Rivoli currently houses an internationally renowned museum of
contemporary art. The hill’s ridge is one of the city’s most important green
spaces, while the largely unused areas surrounding the castle – particularly
those on the southeast – hold potential for urban recreational space of the
first order. The design seeks to use the outdoor spaces sustainably and link
them more closely to the museum.
The prominent southeast slope of the hill, the site of the intervention, takes
on a new key role. Across from the historic approach to the castle on the
northwest side of the hill, facing away from the city, due to its location
between the city’s “back” side and the incomplete garden wing of the castle (its
monumental terraces were never realized), it remained inaccessible and
undefined, an “inner periphery” – for centuries. The divergent scales of the
city and the castle come together unmitigated in this interstitial space. This
tension creates the setting for sustainable, not-for-profit uses, and can thus
be manifest in a positive manner. The design lodges this inner periphery in the
consciousness of the city’s residents and visitors on three different levels: as
urban landscape with a new planting concept, as recreational space within
walking distance, and, by means of the escalators and ramps incised in the
hillside, as a direct connection. The small-scale building components in
coloured concrete and Corten steel, as well as the surfaces wrought in Istrian
limestone, gravel, and rammed earth emerge from the otherwise completely green
hillside.
-Paths and stopping points: The existing narrow streets, which served more to
reroute traffic around the city centre than to provide access to the castle,
have now been closed to automobile traffic and are the framework for the new
system of paths. Embedded in the orchard, a truncated piece of an old street
tied into the overall design via stairs and ramps serves as a place to pass
time. A group of mature cedars shades a new system of stairs that is
interspersed with terraces and flat segments of the path.
Access by escalator: On the side of the hill facing Turin, an intricate pattern
of visual relationships is woven by the cuts in the slope and the traces of the
spaces embedded within the slope, and dynamically frames the specific scales
present in the surroundings – a smaller version of the system of axes in Turin’s
landscape, between Venaria Reale, Stupinigi, Superga and Rivoli. The ascent and
descent take different paths: via ramps, terraces, stairs and escalators, and
through galleries, courtyards and grottoes, a relaxed, rhythmic sequence of
movement, deemed La Ronde, provides surprising views of the buildings in
Rivoli’s historic centre and Turin’s landscape.
