In mid-18th century a new rustic building was attached to the
pronaos of the mausoleum; the rest of the old complex, known then as the
Circus of Caracalla, was almost completely buried, reason why in 1763
Giuseppe Vasi described it thus: The obelisk mentioned is the
Agonalis Obelisk, integrated into the
Fountain of the Four Rivers in
Piazza Navona. Shortly thereafter, in 1825, the property was acquired by
Giovanni Torlonia, who twenty years earlier had already purchased the property of
Roma Vecchia and his marquisate. It was then that Torlonia commissioned the first systematic excavations, although suggested, in the forms and in the completion, by
Antonio Nibby. After eight months of hard excavation (in a field, Nibby pointed out in his dissertation, "
bad and so hard that the tuff itself would have seemed softer") the circus had completely resurfaced to the
Puerta del Triunfo on the street called
Asinaria. And near that door two inscriptions were found, one of which indicated Maxentius as promoter of, and his son Romulus as the one who dedicated, the monument. On describing the excavation, Nibby meticulously observed the mediocre quality of the inscription walls and marble slabs, which therefore dated back to the 4th century. It also pointed out that the building had never been restored in ancient times. The Torlonia family continued to excavate throughout the 19th century (1877, 1883). The archaeological complex was finally expropriated by the
Municipality of Rome in 1943; in 1960, during the
Rome Olympic Games, the entire circus was excavated, as well as the consolidation of the perimeter walls, followed by the partial excavation of the palace buildings, the restoration of the
spina or
euripus, the
quadriporticus and the mausoleum. Several other excavation and consolidation campaigns have followed since then, in 1975–77, 1979 and in the early 2000s. Since 2008, the
Villa of Maxentius has been part of the Municipal Museums system. Since December 2012, the site is part of the
Aperti per Voi (Open for you) project of the
Italian Touring Club, where dozens of volunteers take turns to receive visitors, whose number is constantly growing also thanks to the free access that came into force at end of August 2014. == The complex ==
