The patron of Carpineto Romano is Saint Augustine, celebrated on 28 August in the Convent of Sant'Agostino.
The Palio della Carriera is a costumed historical re-enactment set in Carpineto's period of greatest splendour, accompanied by talks, film screenings and artisanal theatrical and food-and-wine performances. The Reggia dei Volsci Museum displays items from farming tradition and the Palio's costumes. The town also holds the Castello di Pruni.
