The town of Montecatini nestles among the hills of the Cecina valley, a few miles from the city of Volterra. In ancient times it was known by the name of Monte Leone (Castrum Montis Leonis), and was in a constant tug-of-war between Pisa and Volterra, before finally falling under the dominion of Florence in 1472. The history of Montecatini is closely tied to the nearby copper mines of Camporciano, which were exploited from the time of the Etruscans right up the early twentieth century. In the 1800s, they were the largest copper mines in Europe.
