During the time of the crusades the tradition placed the Holy Grail in Mont-Salvat , in the north of Spain, the current Sierra Salvada that closes the Valle de Losa in the north. Three possible sites: San Pantaleón de Losa, Vallejo and Santa María de Siones. "« ... Just five kilometers from this enigmatic hermitage is the small village of Criales de Losa, whose name evokes the root "grail." It is said that, in past times, the place was called "Grails" ... however, the geographical proximity of a mountain range, La Salvada, and a village, Criales, which allude so directly to the legend of the Holy Chalice, is not surprising, since there is no other town in the whole Spanish geography. or place that accumulates such suggestive names. »."
