The Monte Sannace Archaeological Park is home to one of the most important indigenous sites of the pre-Roman Peucetian tribe. The settlement has offered up archaeological evidence dating across a vast period stretching from the Iron Age to the early Roman Empire. The site flourished between the 6th and 3rd centuries BC, and in particular during the Hellenistic Age. In the second half of the 4th century BC, Monte Sannace was enclosed with defensive walls that divided the settlement between acropolis and town on the plain to the west. The archaeological value of the site is complemented by its landscape, which offers visitors the opportunity to fully immerse themselves in the Murge.

The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
