Up to the 15th century, the “Cristinacces” were composed of seven hamlets, burnt down by the Genoese in 1460 as a reprisal for a revolt instigated by Giovani Paolo da Leca, a minor local lord. The village was probably rebuilt about 1480 on the same site, as seems to be indicated by a document of 1485 on the reorganisation of the region after several years of troubles.
