An ancient sanctuary dedicated to Demeter, the Greek goddess of agriculture and fertility, is set to reopen in central Italy on Oct. 24, 2026, following archaeological discoveries that have revealed new details about its history.
The Sanctuary of Demeter at Macchia delle Valli, near Vetralla in Italy’s Viterbo province, has undergone extensive excavations and restoration work. Researchers found evidence that human activity at the site began earlier than previously known, dating back to protohistoric times. The discoveries also shed new light on the sanctuary’s development during the Etruscan and Roman periods.
Excavations reveal earlier history of Demeter sanctuary
Archaeologists recovered artifacts that extend the site’s known history to protohistoric times. The findings suggest that people used the area long before the sanctuary developed into an important religious center.
Researchers also gained a clearer understanding of how the sanctuary’s buildings changed during the late Etruscan and Roman periods. The Etruscans dominated much of central Italy before Rome expanded its control over the region. The discoveries provide further evidence of worship associated with Demeter, a goddess closely linked to agriculture, fertility, and the changing seasons in ancient Greek religion.
Similar archaeological discoveries at a temple dedicated to Demeter on Crete have also revealed evidence of religious activity extending back thousands of years. According to archaeologists, the findings at Macchia delle Valli point to a long history of human activity and religious practices, extending from protohistoric times through the Roman period.
Archaeologists uncover evidence of ancient quarrying
Excavations also revealed previously undocumented traces of quarrying activity. Researchers reached the natural bedrock in several areas and identified evidence of stone extraction. The findings add another dimension to the site’s history, showing how people used its natural resources. The discoveries will help archaeologists better understand how people developed and used the surrounding landscape over time.

Restoration prepares ancient sanctuary for reopening
Conservation work has also restored the site’s historic watering fountain, nearby structures and hillside terraces. These features show how people managed local water resources over many centuries. They also provide evidence that the area remained in use into modern times.
The project was led by Italy’s Superintendency of Archaeology, Fine Arts and Landscape for the Province of Viterbo and Southern Etruria. Funding came from Italy’s National Recovery and Resilience Plan (PNRR), which supports cultural heritage and infrastructure projects. The restoration has focused on protecting the archaeological remains while improving public access. Visitors will be able to explore the sanctuary and its surrounding landscape when it reopens.
