The Etruscan walls mark the perimeter of the “Parco Archeologico Enrico Fiumi,” a lovely garden that now occupies the highest spot in town. You can also see the remains of two Etruscan temples, as well as a fascinating 1st-century basin that the Romans built to collect rain water and distribute it to citizens who lived in lower-lying areas. There’s also an excellent Etruscan Museum (Via Don Minzoni 15), whose masterpiece is an extraordinary wedding urn from the 1st century BC.
From the top of the hill the great the Medici Fortress dominates Volterra. Its large size is visible from many kilometers away and characterizes the profile of the hill on which the city is built. The Fortress was built in 1474, exactly two years after the city of Florence had conquered Volterra at the end of a bitter war for the control of alum mines, an important mineral used in the processing of fabrics.
