 After many vicissitudes the town, which previously belonged to the Pontelandolfo district of the Province of Molise, was annexed to the Kingdom of Italy and in 1861 became part of the newborn Province of Benevento, following an administrative path shared with almost all the other municipalities of today's Comunità Montana.The town, despite its troubled history, started to flourish again in the second half of the 19th century.The patron saint of Campolattaro is St. Sebastian, for whom the town church is named.
