The area of A Saceda tells that the Mouros (the mythical inhabitants of this territory in antiquity) threw a battle axe from A Igrexiña dos Mouros (a possible fortress located in the Serra do Larouco) to A Cidá da Saceda; from there it was thrown back to O Madorriño from where it would be thrown for the last time until it reached A Cidá de San Millao.

This legend, like all legends, hides a part of truth:

1. That the most outstanding archaeological sites on the territory never went unnoticed by the people, who endowed them with legends that mythically explained their origin and function.

2. The war hammer or battle axe that the legend speaks of may have something to do with the same tool that depicts the high relief of an anthropomorphic figure that appears reused in the parish church of Vilar de Perdizes (Montalegre, Portugal). It is possible that it is a pre-Roman God that exhibits two attributes that were highly valued from antiquity: virility / fertility (hence it is represented by a large phallus) and dexterity in the handling of the war hammer or the forge; it could be a Galician-Lusitanian indigenous deity equivalent to the Gallo-Celtic God Sucellus, the Norse Thor, the Greek Hephaestus or the Roman Vulcan.
