Gambassi Terme has always been travellers’ territory. It certainly was during the Etruscan period, located as it is on the road to Volterra, and it was when the Romans came, being a junction on the via Clodia between Siena and Lucca.
In the Early Middle Ages, travellers passed through here, especially pilgrims walking the Via Francigena. Archbishop Sigeric of Canterbury did just this, undertaking the itinerary marking the stops along the way to Rome, mentioning the Parish Church in Chianni, only a short distance from Gambassi’s centre.
