One of the Viking runes, the rune algiz, symbol of master builders on the way to Santiago, present in places such as Nanclares de Oca, Leciñana de Oca, Villafranca Montes de Oca, the hermitage of the Virgin of the Oca or the valley of Anzó. Pilgrims were guided by the way of the daytime ansars and the milky way at night. This ípsilon-shaped Teuton symbol or our capital Greek Y, also used by the Templars, was in Norse mythology a sign of defense and protection.
