The patron saint of Rocca di Papa is Saint Charles Borromeo, celebrated on 4 November.
The third week of September brings the Ottavario della Madonna della Pietà, a centuries-old traditional feast commemorating the miraculous rescue of the town from the 1806 earthquake: the celebration culminates in a procession accompanied by illuminations. The municipal territory also holds the Sanctuary of the Madonna del Tufo, on Monte Cavo, and the Geophysics Museum.
