Stia

thumb|Piazza Tanucci at Stia. Stia is a frazione of the comune of Pratovecchio Stia in the Province of Arezzo in the Italian region Tuscany, located about east of Florence and about northwest of Arezzo. It was an independent commune until it was merged to Pratovecchio in 2014.

==Geography== The town of Stia is often called the "source of the Arno", although the real source is some higher on the slopes of Monte Falterona. However, Stia is the first true village the Arno reaches, where it is joined by another river, the Staggia, that starts at Passo la Calla to the north-east. It is suggested that the name 'Stia' comes from a corruption of the river Staggia's name. As well as the being situated on the confluence of the Arno and the Staggia, Stia also has its own spring that rises in the park of Palagio Fiorentino, which has now been channelled so the water flows from 10 permanent taps.
