Monsummano is known for its precious thermal springs, with warm waters that allow beneficial and relaxing baths. Along with the springs, known since the time of the ancient Romans, the special feature that distinguishes this place of relaxation is certainly the presence of the Giusti grotto: a spectacular underground karst form, famous for its beauty and the therapeutic effects of its steam baths.
The historic core of Monsummano Terme, dominated by the mighty hill of Monsummano Alto, where the ancient walled village stood, owes its birth to Grand Duke Ferdinando I de' Medici, who had the church of Maria SS. della Fontenuova built in 1602. The powerful family knew the area very well because they used the grand ducal properties near the castle of Montevettolini as hunting grounds. And it was in the ancient fortified village that Ferdinand I himself commissioned the construction of the mighty villa that still dominates the high ground.
