A geophysical study in the Herakleia Archaeological Park has revealed traces of a vast semicircular structure that archaeologists have interpreted as an ancient theatre complex.
Located in Policoro, Italy, Herakleia (also known as Siris) was founded in the early 5th century BC by colonists from Tarentum (Taranto) and possibly from Thurii.
Archaeologists from the University of Basilicata recently carried out a geophysical survey that revealed a series of concentric magnetic traces, pointing to the presence of a large and architecturally sophisticated structure.
Based on its form and layout, researchers believe the feature represents a public theater originally built for performances and civic gatherings.
The site occupies a natural slope overlooking the ancient city, directly facing the sanctuary of Dionysus, god of wine and theatre. This alignment reinforces the interpretation of the space as a place dedicated to performance and ritual, intimately connected to the Dionysian cult.
The discovery is part of a research project funded by the National Museums of Matera and the Basilicata Regional Museums Directorate, with support from the Ministry of Culture’s General Directorate of Museums. These institutions have initiated a long-term program combining archaeology, conservation, and community engagement.
“The excavations, directed by Dr. Carmelo Colelli, will provide fundamental insights not only into the identification of the theater but also into the urban organization of Herakleia, founded in 433 BC and home of the Italiot League,” explained Regional Museum Director Filippo Demma. “This project enriches one of the most important cultural sites in the region, ushering in a new season of discovery.”
Director General of Museums, Massimo Osanna, emphasized that the initiative reflects the Ministry’s broader commitment to integrating research within cultural site management. “Investing in research means investing in conservation and the renewal of our cultural narratives,” he said. “Herakleia exemplifies how archaeology, landscape, and institutional collaboration can work together to generate sustainable knowledge.”
