Home Territory of Versilia Culture in Versilia Pope's arbitration award Leo X de Medici Pope's arbitration award Leo X de Medici Pope's arbitration award Leo X de Medici Pietrasanta, for its strategic-military position and for the importance which the town covered economically because of the agricultural and mineral resources of which the territory was rich, it becomes in the years object of dispute and conquest by Pisana, Genovese and Fiorentina, until 1513 when the city and its territory passed definitively, with an arbitration award of Pope Leo X de Medici, under the domination of the State of Florence, following the fortunes of the Grand Duchy of Tuscany until the Italian unification.These are years of political-administrative stability (the Capitanato is born) and economic expansion. It is the time when Michelangelo goes to visit Versilia looking for marble, valuable material for the economy of the time, but also for the future. On September 29, 1513, at the height of Renaissance splendor, Pope Leo X ratified, with the arbitration award, the transition of “Pietrasanta, Motrone and other neighboring countries” from the dominion of Lucca to the dominion of Florence. This resolution determined the birth of a new territorial entity that will remain for centuries linked to Florence and its greatness. This new land, thanks to Pope Leo X, will benefit from political stability, it will take also a full advantage of its marble caves and it will know the flowering of the craftwork that today is the true cultural and economic excellence of the territory.
