Part of the remains of the basilica were converted into a church, generally identified as that of "Santa Maria de Cannapara" which is mentioned in catalogues from the 12th through the 15th centuries. Other parts of the basilica were sectioned off in the medieval period for the use of different trades. The marble workers, or "marmorarii", took up most of the remaining space not occupied by the church in the 11th century for re-fashioning and selling marble architectural ornaments; the eastern aisle was occupied by the rope-makers and was called the "Cannaparia" as a result. In the 16th century, the long-buried site of the Basilica was used as a burial ground for patients of the adjacent "Ospedale della Consolazione".
