Once a prevalently agricultural market town, surrounded by farms and large estates, it is situated six Roman miles from Florence (therefore the name Sesto, Sixth) and underwent a complete transformation of its economic and social prospects in the 18th century when Marquise Ginori founded the Doccia porcelain factory. The production of Majolica and porcelain absorbed most of the labor force in the area and endowed the town with a certain amount of renown even beyond the confines of Tuscany.
Although most of the town buildings are modern, some interesting traces of the past emerge here and there. Villa Corsi Salviati, built in the 15th and 16th centuries, possesses a magnificent garden laid out in the 17th and 18th centuries. In the center of the town we find the Praetorian Palace and the Romanesque Rural Parish Church of St. Martin. Beyond the town of Sesto, in the direction of Prato, one encounters the Museum of Doccia Porcelain, housing examples from the most significant types of porcelain produced over 300 years by one of the most famous and ancient factories in Europe.
