Next to the diocesan museum and inside the space of the cathedral are the curial archives of Gallipoli, made up of about 4310 archival units. These contain archives and historical works from the 16th century to the present. Unfortunately, no document before 1500 has survived, since everything prior was destroyed by the Venetians in the historic battle of 1484. The archives include manuscripts related to pastoral visits, diocesan synods, bishops, excommunications, criminal trials, marriages, curial legislation, parishes, confraternities and monasteries, ordinations, patrimonies, charity, and private oratories.
