Chiusi, Etruscan archaeological site in Tuscany, Italy
Chiusi is a hilltop town near the Umbrian border in the Province of Siena. The settlement sits at about 400 meters elevation and features an ancient network of underground passages that runs beneath its historical center, reaching several meters deep.
The town reached its peak power in the 6th century BC under King Porsenna, who controlled Rome and established major trade routes. This influence shaped the region for generations and left traces in its architecture and development.
The National Etruscan Museum houses objects from the region such as vessels and terracottas that reveal how ancient people here lived and worked. This collection comes from local excavations and shows the craftsmanship traditions of those times.
Visitors can explore the Diocesan Museum and ancient tunnels through a single entrance, accessing multiple exhibition levels throughout. It is wise to wear comfortable shoes and allow time to climb the slope, as the town sits on steep terrain.
Beneath the town lies a striking underground water storage system from the 1st century AD, connected through a dense network of passages. This labyrinth is often called Porsenna's Labyrinth and reveals how sophisticated water engineering was in ancient times.
