The National Archaeological Museum of Lomellina is a state-owned institution intended for public use. Inaugurated in 1998 and expanded in 2006 and 2018, it collects, within some very suggestive spaces of the Castello Sforzesco in Vigevano, the archaeological evidence from excavations or occasional recoveries in the Lomellina area, with the aim of spreading knowledge and promoting its fruition by a large public visiting the city and its monuments. The halls of the Museum host sections relating to different eras, from the prehistoric age to the late ancient and early medieval age. The large hall adjacent to the fifteenth-century stable houses the prehistoric and protohistoric section. The stable is dedicated to the late Celtic and Roman necropolises, which constitute the most significant archaeological documentation of the area. Inside the funerary objects, in addition to the terracotta pottery and metal tools and ornaments, the glasses are particularly noteworthy for their variety and beauty of shapes, and the coroplastics, which, although less refined, allow interesting observations on the funerary ritual. Two other rooms are dedicated respectively to daily life in the Roman age and to the finds of the late ancient and medieval ages.
