Interventions will be carried out to recover the deterioration of horizontal elements, restoring their original appearance and preserving their structural integrity. Moreover, renovation of the plant system will be carried out to ensure efficient and sustainable operation of the greenhouses. The main goal is to enhance this historical and architectural heritage, converting the greenhouses in a place that can host cultural events, exhibitions and other multifunctional activities. The interventions will allow visitors to appreciate the historical and artistic relevance of the greenhouses, offering a unique and valuable experience in Villa Doria Pamphilj.

Project Description: The intervention aims at protecting and enhancing the Arch of the Four Winds and the two quadrangular plan avant-corps that complement it. The intervention will be carried out through a partial renovation of the complex, compatible with the historical nature of the building and its museum-like inclination.
As for the state of conservation, a significant state of deterioration of the non-structural parts of the building is observed, with prevalent plaster detachment from the outdoor cross vaults and parts of cofferered stucco due to the heavy infiltration of rainwater from the flat roof. This also caused the putrescence and the damages to the indoor wooden staircase that led to the top terrace.Moreover, the interiors have been remodelled over the years, which has compromised the original arrangement of spaces and heights.
The restoration progress will include:

• historical-stylistic restoration;
• roof waterproofing works;
• partial modification of rainwater disposal methods;
• re-plastering of the outdoor cross vaults and the cofferered stucco portions of the intrados of the central vault;
• installation of all devices that can improve rainwater drainage and facilitate maintenance work;
• restoration of the vertical elements inside the two building bodies;
• restoration interventions and interior finishing works;
• verification and adjustment of electrical, water, intrusion, fire and video surveillance systems;
• integration of indoor and outdoor lighting system;
• integration of heating and air conditioning systems;
• cleaning and weeding of the outdoor floor with restoration of missing parts.

The planned interventions include the reinforcement of missing decorative elements, the completion of mosaic missing parts, the plastering of damages, the realisation and the positioning on a pedestal of the replica of Diana statue. Moreover, surface cleaning operations and a new lightning system will be planned.

The Dacian prisoner and the Muse aediculae conservative project aims to protect and enhance the relevance of these architectural monuments. The interventions will include:

• biocidal treatment of surfaces to protect them from damages caused by pathogens;
• plaster integration and reinforcement to restore the aediculae structural integrity;
• cleaning and plastering of stone surfaces to remove dirt and deterioration;
• replacement or integration of roofing slate slabs for adequate weather protection;
• final painting.

The main objective is to preserve and promote the Dacian prisoner and the Muse aediculae, allowing visitors to appreciate their beauty and historical relevance in the context of Villa Borghese.

The main intervention activities include:

• adaptation of the ground floor to be used for exhibitions and cultural activities: the ground floor will be adapted to make it suitable for hosting exhibitions and cultural activities. The intervention aims to enhance the Casina dell'Orologio as a multifunctional space and to offer opportunities for cultural enjoyment;
• redevelopment of the interior spaces: redevelopment interventions for the interior spaces will be carried out in order to improve the accessibility, functionality and aesthetics of the building;
• renovation and integration of the existing systems: the existing systems will be renovated and/or integrated to ensure the proper functioning of the building. Modern and efficient solutions will be adopted, respecting the historical and architectural characteristics of the Casina dell'Orologio;
• restoration and renovation of the plaster finish of the exterior, replacement of the frames: the restoration and/or renovation of the plaster finish of the exterior of the Casina dell'Orologio will be carried out in order to preserve its original aesthetic appearance. The frames will be replaced to improve the thermal and acoustic insulation of the building;
• energy efficiency interventions compatible with the regulated nature of the property: solutions will be adopted to improve the building's energy efficiency. These measures will be compatible with the restrictions imposed to protect the historical, artistic and architectural heritage;
• enhancement through the use of interior and exterior lighting design: a lighting design will be developed to enhance the interior and exterior spaces of the Casina dell'Orologio.

The main interventions will include:

• High-grade restoration of the roof: the roof of the reservoir will be restored in order to prevent the façade wash-out caused by incorrect outflow of rainwater;
• restoration of damaged plaster: deteriorated or missing plaster will be repaired and restored. This intervention will contribute to preserving the aesthetic integrity of the reservoir;
• restoration of external access structures: the access structures of the building, such as doors, gates or entrances, will be subject to restoration works aimed at restoring their functionality and aesthetics;
• clean-up of interior spaces: a thorough clean-up of the interior spaces of the reservoir — particularly those near the water reservoir — will be carried out;
• renovation and bringing into compliance of the systems: the systems in the reservoir will be upgraded to ensure proper functioning and regulatory compliance;
• recovery and enhancement of exterior spaces: the exterior spaces adjacent to the reservoir will be renovated, also through the adoption of new lighting solutions.

The main interventions will include:

• renovation of masonry affected by capillary rising damp: solutions will be adopted to stem capillary rising damp, preserving the structural integrity of the building;
• restoration of the rich outdoor decorations: a meticulous restoration of the Uccelliera's outdoor decorations will be carried out, with particular attention to the conservation and recovery of the original stucco ornaments;
• repair of aviaries: the aviaries will undergo restoration works on their architectural and structural elements;
• modernisation, bringing into compliance, and integration of the systems: 
  the existing systems in the Uccelliera will be thoroughly modernised, ensuring regulatory compliance and the integration of advanced technological solutions;
• energy efficiency interventions: measures will be taken to improve the energy efficiency of the Uccelliera, reducing energy consumption and environmental impact;
• enhancement through a lighting design of the exterior: a lighting design will be developed to enhance the Uccelliera during the evening hours, creating an evocative atmosphere and highlighting its significant architectural elements.

The activities will include the structural consolidation of the artefacts and a careful restoration of the frescoes and decorative elements. These interventions aim to preserve the cultural value of the site and promote its enjoyment through the organisation of guided tours and cultural events.

The project involves the implementation of the following works:

• static consolidation works;
• conservative restoration of the building;
• construction of electrical and lighting systems, lifting and water systems;
• removal of architectural barriers;
• museum exhibition dedicated to the most recent phases of the Imperial Fora;
• creation of a Service Centre for the Central Archaeological Area aimed at citizens and tourists;
• creation of a conference room for cultural initiatives and exhibition spaces for small exhibitions;
• creation of an itinerary for the tower and the hypogeal section.

The restoration of the Fontana della Lumaca will include the following activities:

• stylistic restoration;
• reconstruction of the sculptural group of the lumaca (snail);
• restoration of the perimeter profile integrity of the cup;
• overhaul of the water system to put the original jeux d'eau back into operation;
• lighting enhancement.

The restoration of the Fontana della Palomba will include the following activities:

• conservative restoration;
• removal of invasive weeds from the artefact;
• cleaning of the surfaces;
• restoration of the full functionality of the water system;
• lighting enhancement.
