The Ártabros Celtic tribe that inhabited the area until the arrival of Julius Caesar’s troops in the year 62 AD might have contributed to the formation of the place name. In the municipality there are archaeological remains from the Paleolithic Age and in the excavations carried out at the Coastal Site of O Reiro (Chamín) a Mesolithic community and traces of the stone tool industry and mineral prospecting from the pre-Roman era have been found.
The Romans occupied these lands and created a link between A Coruña and the lands of Bergantiños: the Via XX road that can still be seen in the village. The most representative monument of this era can be seen along the river stretch of the route, crossing the stream of Bolaños: the Ponte dos Brozos. It is one of the few authentic Roman bridges that still remain in the whole of Galicia. It is formed by two arches and access ramps with its original paving. It was restored in the nineteenth century.
The rural life style was transformed at the beginning of the 70s by the Industrial Park of Sabón. It meant an exponential demographic and economic increase and it is currently one of the most important industrial areas in the whole of Galicia.
