The parishes are those of O Temple, Cambre, Sigrás, Anceis, San Lorenzo, Cela, Andeiro, Santa María de Vigo, Bribes, Brexo-Lema, Cecebre and Pravio.

If this were true, it might suggest an early invasion of the region by Welsh vikings several centuries ago, though it may well be a semilegendary hypothesis derived from a romantic view of history to link the Celtic people with those of Galicia.

Following the collapse of the Roman Empire and repeated invasions from barbarian tribes from the north, the area came under Suebi protection.

Shortly thereafter, the coastal areas of the province suffered major attacks from the Normans and later by conquering Muslims from the south who sacked the growing town.

One of Cambre's parishes called El Temple has a Romanic church dating from this period and a 14th-century bridge, which suggest great economic and social development in the area.

Following the devastating invasions and battles which took place in nearby A Coruña, most of the population moved inland, along the estuary of the River Mero, to a small village called "Burga do Faro" (today O Burgo).

It was thanks to these three monarchs that a great number of churches were erected in the region and also several bridges throughout the area were built in a short span of time.
