The myth is a complex structure of facts diluted in stories, which make up the plural and individual imaginary. Stories formed by the accumulated human experience and its relationship with the surrounding environment, embracing in it the memory of the past and an expectation of the future. A collective unconscious that remains latent through generations, intrinsic to rituals, practices and legends. By word of mouth, from cycle to cycle. The identity of a nation is built on this network of tales and shaped over time. More than a common border, the northwest of the Iberian Peninsula shares a common genome since ancient times. The myth permeates borders and territories, through the people. Roaming through these territories, which one day were the lands of the end of the world, Oestriminis, becomes the reunion with a distant past of tribal traditions. This awareness allows us to look more broadly to issues of identity and contemporary divisions, differences and similarities. The theme is the myth, the elements are the vestiges. Tracks left in the rituals, which are still practiced today, in the people who live and disseminate them. Legends and beliefs that show up as the cornerstone of the culture. More than an ethnographic view to categorise the territory, the proposal is of an interpretative vision, in which, as in its own myth, the line between the real and the imaginary becomes difficult to discern and easily crossed. Beyond what currently exists, this is a search for what has also existed, a search for an origin, a root.
