The preservation project includes a wide range of activities aimed at maintaining and redeveloping the monument that will include:

• maintenance of the monument's interior and exterior stone surfaces such as: the quadriporticus, the marbles of the crypt/ossuary, the bases of the flag stands, and the columns of the sacred area. The interventions performed will include washing, cleaning, disinfection, weeding, extraction of soluble salts, removal of grout that is no longer functional, and redoing new grout. Inspection of the mosaics in the hypogaeum environment will be planned, with possible fixing and grouting of detached tiles;
• cleaning of the entire floor area, including washing, disinfecting, weeding, and, if necessary, grouting to seal any cracks or damaged grout;
• maintenance of the bronze surfaces of the 4 braziers and braziers access doors by cleaning, corrosion inhibitor treatment, repair of lesions or gaps, and application of an appropriate protective coating;
• arrangement of the paving slabs, which will include disassembling and rearranging the slabs of the stallage at the base of the stairs to ensure the safety of visitors, as well as disassembling and arranging the manhole area before the descent to the service rooms;
• removal of sections of monumental travertine fencing on the north side, followed by reinstallation on axis at a higher elevation to allow for detachment from tree roots;
• removal of plaster degraded by mould and moisture within the service rooms, followed by the resurfacing of a new osmotic dehumidifying plaster and the application of an appropriate paint job;
• arrangement of the access door to the service rooms;
• removal of paint layers and new painting of all metal elements in the area, such as gates, fences, doors, etc.
• verification of the stormwater runoff and channelisation system by replacing the downspouts and introducing new collection grates to collect water from the entire stallage floor area;
• check and replacement of the electrical panel, as well as implementation of outdoor lighting in the area;
• installation of a new video surveillance system connected to the Administration Monitoring Centre;
• making new signage, poster structures, multilingual and tactile cards to support the visit;
• creation of a video tour of the area for website promotion and possibility of viewing it on tablets for visitors with mobility disabilities as an alternative to descending into the crypt;
• aesthetic review and functional adjustment of the existing lodge to create an information, educational and control and management point for the area.

The activities constitute a comprehensive project to preserve, enhance and improve the monument, ensuring its safe use and long-term preservation.
