The museum, founded in 1897, contains the most remarkable finds come to light in the course of the excavations in the Samnite necropolis of Alfedena-Campo Consolino.

The digging operations, which Lucio Mariani started at the end of the nineteenth century, brought to light interment tombs dated from the VI to the IV century B.C. and rich funeral arrays, among which a bronze belt, a Samnite three-disk breastplate and two pieces of armor covering the chest named kardiophylakes.
