The conservation project focused on the restoration of the two hemicycles, the related fountains, and the sculptural apparatus located in the square. The restoration of the travertine roofs and the general maintenance of the brick curtain were included in the interventions.

The preliminary activities related to the verification of the sculptures that adorn the hemicycles in order to evaluate their integrity. The restoration of stone surfaces and metal elements included consolidation, chemical and mechanical cleaning, biocidal treatment, verification, removal, and reconstruction of non-functional grouting. The metal connections were replaced, with a consequent aesthetic revision of the entire complex, including the application of anti-graffiti measures.

As regards the fountains, the waterproofing layer of the water basins was restored, the condition of the screeds was checked and any damage was sealed. Washing, localized consolidation, extraction of soluble salts, disinfection, weeding, re-grouting, and, replacement of damaged elements were carried out on the brick walls. Furthermore, verification was carried out on the functioning of the water systems and the artistic lighting of the two fountains.

This conservation project aimed to restore and preserve the integrity of the structures, sculptures, and fountains, ensuring their long-term functionality and protection.
