Mangona
Mangona lies in the hills north of Florence, beneath the remains of a castle that gave its name to a small county. The Alberti counts held the fief from the twelfth century. In 1332 Margherita degli Alberti sold the county to Pietro de' Bardi, whose acquisition of castles near Florence alarmed the city's government. A customs house was built near Mangona in 1788 and remained in use until the county of Vernio was absorbed into Tuscany in 1814.
