Crossing the threshold of the current doorway placed along the front of the cyma moulding, one reaches the original entrance, which opens on a barrel-vault entrance hall. Having passed the hall, one enters an astonishing landscape where wild vegetation covers the vast open space and the Fort’s sloping walls.
The state of abandonment made the Fort evolve into a natural oasis where a great diversity of animals can find refuge; a green lung of pulsating life that must be made available to the public.
The project is meant to control the vegetation in the area by careful pruning, in order to clear the passages and the ramps on the upper and lower ramparts, while preserving the solid landscape.
Walkable paving, which will be photovoltaic, will cover the Piazza d’Armi and supply the whole Fort with energy.
The wide-open space of the Piazza will become a catalyst of energy and will attract activities, producing the sufficient amount of energy necessary to set in motion the elements placed on it.
Imagine a peaceful siege of the Fort, where an active citizenry takes possession of a characterising part of the area to overturn its paradigm: war turns into a game.
While the signifier remains the same, the meaning turns upside down. The fortifications, structured to be unassailable, are conquered by the citizenry and transformed into places devoted to relaxation and entertainment.
Like during a barricade, from the parterre of Piazza d’Armi, provisional structures will emerge, whose features remind the viewer of the ancient sighting turrets. But in this case, they will support screens that project open-air films. Consequently, the sloping walls will be used for climbing activities and the Trojan horse as a game for children, for example.
In compliance with the competition announcement and conforming to the constraints to which the Forte Portuense is subjected, all the interventions in Area 2 are to be considered provisional and/or removable.
Inside the Fort, numerous and diversified activities come in succession, but they can be summed up in two areas: a wellness area (athletic circuit, spa, massage and relaxing areas, wine bar-restaurant) and a didactic-cultural one (newspaper and periodical library, multimedia library, laboratories, polyvalent rooms, exhibition areas). These areas are conceived in such a way to support the citizenry but mainly to encourage a larger touristic base to visit the Fort located in this historical, though remote area, relative to the old town centre. Along these lines, the fortified ring can be rethought to make the suburban areas more attractive and to suggest an alternative track to the capital’s better-known touristic destinations.
Services for the neighbourhood, such as kindergartens, senior and community centres will remain situated outside the grounds of the Fort, but will be merged on the South-East side of the hill, so that they can clear the area between Via Portuense and Via Irlandesi and make it a public park.
The logic behind the buildings is the formal one of the fortification. Some places and the connective elements are hypogeum, while the classrooms and the meeting rooms stick out of the hill’s profile partly built on the northern front to return an image of the surrounding that could be faithful as much as possible to the original.
The area surrounding Forte Portuense is conceived as beneficial for the whole neibourhood.
The community Centre, the kindergarten and senior Centre, originally distant, have been set on the south-west wing of the Irish Hill to create a unique catalyst for the citizenry of every age.
Considering the formal logic of the Fort, the project requires hypogeum areas as connective elements, while the classrooms and the meeting rooms or the didactic and playing ones stick out of the hills profile as a telescope on the city.
The intervention is meant to recreate a closer connection between the Fort and the Hill which is partly absent today.
The grass land covering the buildings should be equipped as a children playground, whereas the community Centre and the senior Centre should be planned as a public park to form a single green line surrounding the Fort.
On the North side of the hill, at the crossroad between via degli Irlandesi and via Portuense, the original access will be reopened, if possible, the character of the ancient ravelin and the courtyard will be rebuilt.
These improvements are aimed to spotlight the monumental entrance which now remains hidden due to the actual access to the Fort which is along the ditch tangential to it.
The open spaces inside the Fort are organized on different levels so to have a variety of activities contemporarily.
The dry ditch running around the wall can become a jogging path with several equipped areas.
Piazza d’Armi is the bulk of the project, the place where everything is possible.
An elevated section pavement will run along the open space to end only before the Army Quarter, leaving the original tiles visible.
The walkable paving is a vital element made of photovoltaic tiles with a slip resistant treatment and backlit by a led technology to create a lively night vision due to trick of light; a blank slate from which animated objects created by the electricity of the same pavement, appear.
The project is meant to create multiple combinations to be alternated in order to satisfy the necessity of a continuous update.
The upper levels and the central crossbeam are conceived as a relaxing area, the stairs and walk paths, free from bushes, will become a pleasant promenade in a vegetation which hides animal species as foxes and barn owls.
The conservation intervention aims at protecting the historical integrity of the Fort.
Hydrated lime will be used on walls, as it should have been in the origins. A walk over steel surface will be fit in the rooms without pavement.
In the Fort internal spaces, numerous and diversified activities come in succession, but they can be summed up in two areas: a wellness area and a didactic-cultural one.
The wellness starts with a sensorial path: a heated and scented space lying on the west wing of an underground ring gallery leading to massage rooms upstairs and steam room in the half caponier.
Half of the space in the Army Quarter is occupied by a thermal spa in the Roman style.
There are three pools in sequence with water at different temperatures (frigidarium, tepidarium, calidarium) which are lifted on the pavement so to let pipes pass through.
Two rooms humid and heated (assa sudatoria e laconica) are next to the calidarium and even a second thermal spa inside central caponier.
Walking along the longitudinal corridor there are two main stairs to reach tiny rooms used for relax.
The choice of a thermal spa in the project is due to the presence of an ancient spa, Pozzo Pantaleo, which has recently been discovered during the excavation works in via Portuense.
A strategy to connect present times to the ancient Imperial and Risorgimentale Rome.
The other half of the Army Quarter hosts didactic and educative spaces as, multipurpose rooms, rooms for district association, multimedia library, periodical library, toy library, laboratories: polyvalent spaces to be used for different purposes.
The west wing of the ring gallery is dedicated to temporary exhibitions and the rooms upstairs are aimed at hosting temporary atelier for artists.
The crossbeam rooms, where in origin werw the kitchen and vivandier, in the project hosts the wine bar and the restaurant with a season menu using local vegetables, typical of the agro romano.
SUSTAINABILITY
Energy sustainability is a focal aspect of the project. The photovoltaic surface that covers the Piazza d’Armi ensures energy supply for both rooms in the Forte and the spaces that constitute the square.
It consists of a steel substructure spliced to a system of supports that lift from the ground of about 20 cm, in order to allow the disposal of rainwater and the passage of the installations.
Onyx Solar photovoltaic tiles are non-slip and are able to support up to 400 kg load, which makes them appropriate for pedestrian traffic.
The choice of the backlight with LED technology suggests different visions of the night obtained through the modulation of the light sources in order to create interesting lights involving all or part of the pavement.
Whereas, in the total absence of artificial light, you can imagine, that the sky mirrors on the night surface as it does during the day.
In addition to the PV system, the project provides a further implementation of the system in space heating, using one of the most interesting technological aspects of the Fort: the dense network of canals connecting all the spaces.
It is possible to use this ventilation system to capture the steam produced by the people passing within the rooms. The hot air, lighter, rises up and it passes through channels hidden in the arches, to the premises where it is intercepted by a heat exchanger (a coil) containing a liquid cooler, which heats up under the first law of thermodynamics.
The heat produced is then transmitted to the heating system.
The buildings that are located in the compendium are partly underground, a feature that increases the potential for cooling. The extension of the contact surface with the soil influences the thermal inertia of the building, whose wall becomes integral with the ground itself, and it shares the characteristics of high thermal capacity.
A further improvement in performance can be obtained by associating a heat exchanger basement to the ventilation system. The underground heat exchanger is constituted by a system of pipes laid at a depth of 100-200 cm, such as to ensure a temperature of the soil, which is relatively stable over the year. The air taken from the outside, even before arriving to the heat exchanger and the air-air ventilation system inside the building, flows through the pipes with the result of heat in winter (for example from 0 ° C to 10 ° C) and cool in summer (for example from 30 ° C to 25 ° C).
