The patron saint of Campomarino is Saint Christina, whose patronal feast is celebrated every year on 24 July: the saint's statue is displayed in the church of Santa Maria a Mare. The day before, on 23 July, Saint Anne is traditionally celebrated, patron of the hamlet named after her and co-patron of the whole municipality, whose church bears her name.
Campomarino's religious calendar also includes the feast of the Assumption, on 15 August, when the painting of the Madonna Grande, displayed on the high altar of the sanctuary of the same name, is carried in procession. The town also preserves the church of Santo Spirito and the one dedicated to Saint Anthony of Padua and Saint Gabriel, as well as the Torre Ramitelli.
