Trinitapoli located on the lower part of Tavoliere of Puglia, is a rich area of Hypogeum "underground tombs and pre-Christian temples". The prehistoric archaeological exhibits are exposed at the local Museum of Ipogei. In the Archaeological Park of Trinitapoli there are two hypogeums: one known as "of the Bronzes" and the other "of the Avori".
