In 2011, as part of an ongoing redevelopment project, excavations were undertaken in the Circus Maximus.

The excavation of the monument’s exterior, in reality carried out in the 1930s, uncovered the external road and the structures relating to the building in front, perhaps a horreum, as documented by the Forma Urbis. Several rooms, perhaps tabernae, faced onto the road. Three were found on the eastern edge of the road, together with a network of sewers, which included a very large drain. The excavation of the tabernae was limited due to the need to construct the roadbed for the road surface above. A tank/drinking trough constructed in travertine blocks situated between two of the circus’ piers was also uncovered.

Overall, the entire area appears to have undergone various interventions which, during the course of time, reinforced the structure and also affected its practicability, in particular following the construction, in the imperial period, of various buttresses to support the vault of the external walkway and façade.
