It was a thriving medieval craft center and suffered considerable damage in the disastrous earthquake that hit the area on 11 April 1837.
This earthquake caused the disappearance of the underlying center of Uglianfreddo (not to be confused with Uglianfreddo ai Cerri in the municipality of Fivizzano).
