Mentioned in documents since 1224, the castle of Monteggiori used to be property of the Lords of Bozzano. We lack information about its construction; it was occupied by Lucca in 1224 and so shared the fate of the castles of Montemagno, Corvaia and Vallecchia that all fell into the hands of Lucca between the XIIth and XIIIth century. At this time the territory of Camaiore and all Versilia was theatre of the bloody struggle between Lucca and Pisa for the control of the coast and was gradually taken away from its original owners, the local lords.
