In May-October 2010 the Rome Superintendency renewed excavations, begun in September 2007, in the area of Piazza Augusto Imperatore with the aim of acquiring new data of use in the planning of the modernisation of the piazza.

The excavation looked at the sector occupied by the remains of the Oratory of San Rocco which had been demolished in the 1930s. The first phase of work saw the removal of several overlying floor levels, dating to different phases of the oratory’s life and demolition of the surviving foundation structures.

The Renaissance floors sealed a series of deposits obliterating the Roman levels and nine burials were found within them. Only four of the burials showed the use of large tile fragments and amphora walls, the other were in simple earth graves. This group of burials was part of the already known late antique necropolis of the Mausoleum of Augustus, mainly excavated without documentation in the 1950s, the graves being concentrated in a limited area, on axis with the front of the mausoleum. A preliminary analysis of the materials from the layers cut by the graves produced nothing earlier than the end of the 4th-beginning of the 5th century A.D. and thus a terminus ante quem non for the dating of the cemetery.

The removal of the dumps completely exposed a structure on an east-west alignment, constituted by reused blocks of travertine and marble, positioned directly upon a Roman paved surface. A number of blocks decorated with bay tree branches in relief were also reused in this structure, largely visible at the end of the previous campaign.

Immediately south of the latter, and parallel to it, was a partially preserved structure constituted by smaller and more irregular marble and travertine fragments, positioned up against the terrain probably to function as a containing structure.

Below the structures described a new, large area of travertine paving came to light, dating to the Imperial period, situated at 10.58 m a.s.l., and connecting to the part uncovered in the 1950s and that which emerged during the 2008-2009 investigations.
On the opposite side, a small trench opened to the east revealed another patch of paving corresponding to the eastern limit of the paving in front of the mausoleum. Moreover, a longer section of the Roman sewer, on an east-west alignment and delimiting the paved area to the south, was investigated. This structure, known in the modern era as the Chiavica di Schiavonia, had been seen and documented by Baldassare Peruzzi when the church of San Rocco was built.
The demolition of the structures belonging to the block between via degli Schiavoni and vicolo del Grottino was extended to the west, and this revealed the conglomerate foundations of the structure in travertine blocks, discovered in 2008-2009 to the south of the ancient sewer.

In the eastern sector of the piazza the demolition of the foundations belonging to the block owned by the Croatian College also continued. The structures were removed down to the level of 12 m a.s.l. as foreseen by the modernisation project. The Renaissance levels sealed the remains of late antique buildings with mosaic floors. The greater part of these structures continued beyond the excavation area; thus they are of difficult interpretation. In the same sector a series of progressive rises in the ground level of the area were identified, formed by dumps with related floor levels; all of this stratigraphy can be attributed to the Roman Imperial period.
