 The small museum, built by the Superintendence and Count Jacopo Marcello, was inaugurated on 29 May 1960 and consisted of two rooms, one of which was used as an exhibition space divided into two rooms, the other as a warehouse of archaeological finds; in the outer porch are exposed some tombstones.Until then, the number and above all the importance of the excavations in the area in question, under the management of the Archaeological Superintendence, had been extremely low.Since 1966, however, numerous excavations have been carried out in the area of Via Annia, which brought to light more than 2000 finds of tombs and burial places.
