Los poblados fortificados en la Valleriana (Pescia, Pistoia, Italia). Análisis de la forma urbana del Castello di Pietrabuona

During last March 2011 was carried out an multidisciplinary expedition to survey the city of Pietrabuona. The data has provided a lot of information that makes possible the detailed documentation of the entire settlement. Pietrabuona Castle was built by the Bishop of Lucca, Pedro II (896-933), to control of the eastern frontier of the possessions of his diocese. The medieval center, consisting of a main road with buildings on both sides and at the bottom the noble palace, has been gradually increasing to their final structure after being conquered by Florence in 1364. Communication concerned the old town hall and the church of San Matteo in Bicciuccolo, built along the XIVth century. Both buildings are face to face forming a small square in the town center, on which we can study the relationship between these edifices, showing the civil and religious powers of the Tuscany Middle Ages.
