Ponsacco is a town in the province of Pisa with a population of about 6000 inhabitants and a rich historical past. Visiting the city, the St. Giovanni 's Church and the Madonna della Tosse's oratory can be admired, while the Medicean Villa of Camugliano is located in the neighbourhoods.

Different interpretations disagree over the origins of the local place name. Many link it to its Roman origins putting it into relation with a "village loot", namely a plunder which took place in the small village in the imperial era. Others claim that it can derive from "Ponsanus", that is "Ponte della vecchia", or "Ponsa salis", with reference to the salt trading activity.
It was first mentioned in some ancient documents that were drawn up in a place called "Pons Sacci" dating to 1197. Known with this name, the castle, which today corresponds to the downtown, immediately benefited from a favourable strategic position at the borders between the Republics of Pisa and Florence.
The continuous skirmishes for its possession between the two cities led to the rapid fortification of the village.
In 1341, the Ponsacco fortress was the only to resist a strong attack by Florence, which broke through the territory of Pisa to disturb an action led against Lucca by the seaport republic. Since then, the Pisan doge chose Ponsacco as his residence.
On several occasions, the city underwent sieges and pillages until 1406, when it went under the direct control of Florence. Later, it became the base of a town hall with governors coming from Florence.
In 1494, Ponsacco rebelled and returned under Pisa 's control, but its reconquest only lasted one year. Once Florence took the town back, Ponsacco's gates and walls were pulled down in 1509 and, with this demolition, the town definitively entered the Tuscan Grand Duchy era.
During the Medicean period (from 1513 to 1737), the town was designated as a marquisate by Ferdinand II and given to the Niccolini family. It also became the base of the Feudal Commissary, a legal office similar to the podestà or vicar, from 1637 to 1781. Later, the town remarkably intensified its agricultural and trade activities under the aegis of the Lorraine, also through numerous road works wanted by the new rulers.
More activities developed during the Napoleonic occupation (1801-14), among which there was the production of furniture, which is still today the most important economic resource in the town.
