Galluzzo is part of quartiere 3 of the Italian city of Florence, Italy, located in the southern extremity of the Florentine commune. It is known for the celebrated Carthusian monastery, the Galluzzo or Florence Charterhouse (Certosa di Firenze or Certosa del Galluzzo), which was founded in 1342 by Niccolò Acciaioli.
Galluzzo was an autonomous commune until 1928, at which point its territory was split: part was assigned to the commune of Florence in accordance with the 2562nd Royal Decree (01/11/1928), which foresaw the expansion of the Florentine administrative territory (together with the fractions of San Felice ad Ema and Cascine del Riccio); the rest was assigned to the newly formed commune of Scandicci (known as Casellina e Torri until that same date) as the fraction of Giogoli; or to Bagno a Ripoli (Grassina). The remainder formed the present commune of Impruneta.
At the time in which the commune was disestablished, it had circa 22,000 inhabitants and was undoubtedly the most populated commune of the Florentine province, after Prato and Empoli; its communal territory bordered on those of Florence, Casellina e Torri, San Casciano in Val di Pesa, Greve in Chianti and Bagno a Ripoli. The commune, which at the time of national unification extended roughly 68 km2, had already undergone a previous reduction in 1865, which with the 2412th Royal Decree (26 July 1865) had lost a strip of land between the city walls and Due Strade to the commune of Florence.
Some trace the origin of the curious name (a variation of the word "gallo", cockerel) of the suburb to the Galluzzo or Galluzzi noble family, who were the regional "biadaioli", and whose crest was a golden cockerel in a blue field. Others maintain that the name Galluzzo derives from the old tavern located on the road leading to Rome from Florence (Via Cassia), whose sign was a cockerel. However, this sign was simply a reproduction of the carving of a cockerel on a milestone on the side of that same road. This latter hypothesis is more likely, given that even the historian Andrea Dei in his "Cronaca Senese" of 1253 states that "a company of armed Sienese and Pisans performed a quick raid into Florentine territory as far as the Galluzzo stone, and as a token of disrespect cut off the cockerel's head".
