The museum is housed in historic Palazzo Antignano, whose foundation dates back to the ninth century and incorporates the remains of San Lorenzo ad Crucem, a small church of the Longobard period. The museum has an archaeological section and a medieval section, as well as an important library, three large courtyards and a garden adjacent to it. The museum prides itself most on its collection of ‘Mothers’, consisting of a large number of tuff statues (from the 6th to the 2nd century B.C.), almost all of which depict a seated woman, with one or more infants in her arms. These have been identified as ex voto used in the cult of the Mater Matuta, an ancient Italic divinity of daybreak and birth, who was also worshipped in ancient Capua.
