Recreación dos ataques viquingos que na idade media sofrian as vilas galegas. Entre elas a de Iria FLavia, antiga vila romana, que era o porto mais achegado a Santiago de Compostela que de aquela tiña riquezas ancelladas polos piratas nordicos. No seu camiño as Torres do Oeste, derradeiro valuarte para impedir a sua chegada dende o mar.
Dende mediados do seculo XX todolos primeiros domingos de agosto, representase a sua chegada na que veciños de Catoira se disfrazan de Viquingos sedentos de viño e veñen desembarcar a carón das ruinas das torres do Oeste. Viño e festa a esgalla.

Recreation of the Viking attacks that the Galician villages suffered in the Middle Ages. Among them that of Iria FLavia, an ancient Roman town, which was the closest port to Santiago de Compostela, which at that time had riches coveted by the Nordic pirates. On their way to the West Towers, the last bastion to prevent their arrival from the sea.
Since the middle of the twentieth century every first Sunday in August, represents the arrival of the invaders in which the residents of Catoira disguise themselves as wine-thirsty Vikings and come to land next to the ruins of the towers of the West.
Wine and a great party.
