The Valdarno Inferiore area covers a large area partly flat and partly hilly, marked by the presence of the Arno river, which flows from the city of Florence to Pisa and then flows into the Tyrrhenian Sea. Along its route, the river meets villages that have distinguished themselves in history for their important position, being displaced from Pisa, Florence and Lucca. These small medieval towns still retain their original shape and important traces of their glorious past. Many information can be found by visiting the museums of the Valdarno Museums network, which this website wants to highlight. The municipalities that have joined the Museum System of the Valdarno di Sotto are: Castelfranco di Sotto, Fucecchio, Montopoli Valdarno, S. Miniato and S. Maria a Monte.
