The patron saint of Serravalle Scrivia is Saint Martin, celebrated on 11 November with stalls along the town's streets and a funfair.
On the third Sunday of September, the patronal feast of Our Lady of Sorrows is held, with a procession and craft stalls in the historic centre's main street. On the evening of 15 August, the Procession of the Assumption is instead held, organised by the Oratorio dei Bianchi. The municipal territory also holds the archaeological area of Libarna and the Roman bridge on the Via Postumia.
