The Mugello (Italian pronunciation: [muˈdʒɛllo]) is a historic region and valley in northern Tuscany, Italy, corresponding to the course of the River Sieve.
Then the region was occupied by the Etruscans who left many archaeological traces and who built the first road network of the Mugello.
The subsequent Ancient Roman conquest and colonization of the Mugello region dates back to the 4th century BCE.
It is not only testified by several finds such as tombs, coins, and walls, but also, through toponymy, e.g. names of places ending with the praedial suffix -ano (Latin -anus) or -ana: Cerliano, Figliano, Marcoiano, Galliano, Lucignano, etc.
In 1999 a dam was constructed across the Sieve river, forming the reservoir of Lake Bilancino in the Mugello valley.
