The castle of Gello Mattaccino is located in the municipality of Casciana Terme Lari.
In this ancient fortification there was the church of San Martino in Gello, that dates back to 764 d. C.
The name derives from “Gellum Mathaesi Cini”, who acquired this estate during the period when Cosimo I reigned in 1550. He supported a dispute with the municipality of Santa Luce for border issues.
In the nineteenth century the Pordenone family Rosselmini owned the estate and the annexed mill fed by the ditch of the Giunco Marino.
