The presence of olive trees in Galician lands dates back to Romanization. During the Middle Ages, the Kingdom of Galicia was punished by the Catholic Monarchs through the felling of olive trees, although this species managed to survive in areas of the south of the province of Lugo, where the benefits of the Mediterranean microclimate create an ideal habitat, which allowed the consolidation of a small artisanal production of extra virgin olive oil that was once produced in the oil mills existing in the municipalities of Quiroga and Ribas de Sil.
