The hypogeum Bellacicco is a hypogeum structure. Its peculiarity which makes this structure unique all over the historic and artistic landscape of Taranto is that in it we can find records of all the ages and the historical periods dating back from Taranto's foundation by the Spartans up to the XVII century, date of the building of the homonymous noble palace. The hypogeum is divided into 4 rooms (5-8 metres hight) and shows an extension of 800 square metres and a depth which reaches, at the lovest levels (4 altogher) 16 metres under the street basement and 4 metres under the sea level. The structure, in central position as regards the isle of the historic centre, represents a crossroad with the other hypogeum structures of the ancient village that constitues, on the whole, the system of "Taranto Underground" that reaches and radiates just from the hypogeum de Beaumont Bonelli Bellacicco.
