Todi

Todi is a town and comune of the province of Perugia (Umbria) in central Italy. It is perched on a tall two-crested hill overlooking the east bank of the river Tiber, commanding distant views in every direction.
In the 1990s, Richard S. Levine, a professor of architecture at the University of Kentucky, chose Todi as the model sustainable city, because of its scale and its ability to reinvent itself over time. After that, the Italian press reported on Todi as the world’s most livable city.
According to the legend, said to have been recorded around 1330 BC by a mythological Quirinus Colonus, Todi was built by Hercules, who here killed Cacus, and gave the city the name of Eclis.
Historical Todi was founded by the ancient Italic people of the Umbri, in the 8th-7th century BC, with the name of Tutere. The name means “border”, being the city located on the frontier with the Etruscan dominions.
