The patron saint of Ceprano is Saint Arduinus, celebrated on 28 July in the church of Santa Maria Maggiore, known as Sant'Arduino.
Every year, in October, the Palio delle Corti is held, a historical re-enactment of 13th-century events linked to Manfred of Sicily. The town also holds the Church of the Annunziata and the Church of the Sacro Cuore.
