The defeat of Maxentius by Constantine probably led to the early abandonment of the site (it is believed that the racecourse was never used by Maxentius), and the property passed to the "Patrimonium Appiae" (already mentioned in the time of Pope Gregory I -in the late 6th century- among the ecclesiastical heritage). The circus, called «"Girulum"», is mentioned in a land-transaction document between ecclesiastical entities in 850.
