Work at the Circus Maximus, at the semicircular end, concerns the conservation and enhancement of the monument, in particular the consolidation and restoration of several sections of wall and its modernisation from a planning-environmental point of view. The objective is the creation of a useable space, with a uniform and easily accessible ground surface. Therefore, a number of specific interventions were undertaken, together with careful cleaning in areas that were heavily altered in the 1930’s and 40’s, when the monument was used as a site for exhibitions and recreational activities.

The most important find was made along the circus’ substructures, on the Aventine side. This was a heavily damaged and cut part of the internal structure of cement conglomerate. The cleaning of other sections of the brick wall of the ima cavea provided a relatively complete picture of this sector of the seating tiers and of the system of vomitoria providing access to them. To the exterior, in fornix VI, a taberna was identified, its opus spicatum floor quite well-preserved. A large dolium (diameter c. 1.30 m) was embedded in the floor, the fill of which has yet to be excavated.

The Moletta tower (cited in documents from 1145 onwards) was also investigated. The investigation inside it, undertaken in order to check the building’s stability, produced interesting results. A number of floor levels were identified, linked not only to the variations in the exterior ground level, but also to changes in use during its occupation.
Lastly, during work to modernise the ground surface in the area corresponding with the track, the foundations of a craft-working structure (late 1800-early 1900s) were uncovered, together with walls and large blocks of reinforced cement probably relating to the Mostra Autarchica del Minerale Italiano (1939-1940).

During 2012, a number of interventions relating to the general organisation of the archaeological area were completed, such as the new fencing and the viewing terrace, the installation of services and the system to contain the earthworks. At the same time work to consolidate and restore parts of the eastern hemicycle began.
