Acropolis

History and Results of the Archaeological Investigations

The archaeological investigations carried out on the Acropolis plateau have made it possible to reconstruct an almost uninterrupted historical and architectural sequence. This extraordinary archaeological record spans more than four millennia, from the Copper Age to the Late Middle Ages.

History and Research Methodology

The scientific rediscovery of this key site in northern Etruria has been marked by three pivotal phases, each of which has reshaped our understanding of its historical development. As visitors move through the different scenes, they encounter artifacts and structures from successive periods, arranged in chronological order. Each element is carefully placed within the virtual environment to reflect its historical context, allowing visitors to follow the evolution of the Acropolis while maintaining a seamless and immersive experience.
1926 | Doro Levi
Initiated the first systematic excavations at the Piano di Castello. He uncovered the eastern side of Temple B before the work came to an unexpected halt.
1967–1972 | Mauro Cristofani
Working on behalf of the Italian Archaeological Superintendency, Mauro Cristofani identified the remains of the two great Hellenistic temples (A and B), laying the scientific foundations for understanding the origins and urban development of Volterra (*poleogenesis*).
Since 1987 | Marisa Bonamici
Marisa Bonamici has directed annual systematic excavation campaigns that have transformed our understanding of the site. Using a multidisciplinary approach and rigorous stratigraphic excavation—combining archaeology, architecture, and geology—her team has explored the western sector, revealing the Acropolis’s Archaic phases and providing new insights into the religious practices and cults of the ancient citadel.
Excavation Findings: Four Millennia of History
Stratigraphic excavations have confirmed that the sanctuary was established on a site that had already been densely occupied during earlier periods, reinforcing the Acropolis’s role as the true driving force behind the development of the settlement.
2300 - VIII sec. a.C.
1. The Pre-Sanctuary Phase

Archaeological investigations have uncovered around one thousand pottery fragments dating to the Bronze and Iron Ages. These materials were recovered in a secondary context—that is, from layers used in antiquity to level natural fissures in the bedrock or as fill within the podiums of the Hellenistic temples—confirming that the hilltop was continuously occupied as early as the proto-urban period.

VII sec. a.C.
2. The Foundation of the Sanctuary

The excavations beneath Temple A uncovered a section of the earliest temenos—the stone enclosure wall surrounding the sacred precinct. Dating to the second quarter of the 7th century BC (675–650 BC), it is the earliest known example of its kind in northern Etruria.

VI - V sec. a.C.
3. The Archaic Monumentalization
This phase marks a significant leap in architectural development. Archaeologists have identified the remains of a small shrine decorated with Campanian-style terracottas and, later (around 480 BC), a large Tuscan temple whose decorative elements testify to the work of highly skilled craftsmen from the major southern Etruscan center of Caere (modern-day Cerveteri).
III - II sec. a.C.
4. The Monumental Layout in the Hellenistic Period
The site reached its most impressive—and still visible—monumental phase with the construction of Temple B (late 3rd century BC) and Temple A (mid-2nd century BC). Research Spotlight – The 2014 Excavation Campaign: Excavations in an area east of Enclosure I helped fill a significant gap in our understanding of the early Hellenistic period. The investigations revealed the unexpected presence of metallurgical production within the sacred precinct, uncovering a small bronze-working furnace, metallurgical slag, and crucibles.
III - XV sec. d.C.
5. The Post-Classical and Medieval Period
Following the gradual abandonment of the sanctuary during the 3rd century AD, the area underwent a profound transformation. In the 13th century, a thriving medieval quarter developed here, housing several important buildings, including the bishop’s palace. This chapter in the site’s history came to an abrupt end in 1472, when the entire district was razed by Florentine troops led by Federico da Montefeltro.
