Asturias Day is observed in the autonomous community of Asturias in northwest Spain every September 8. This official holiday coincides with the feast day of Our Lady of Covadonga, the patroness of Asturias, and the Nativity of the Blessed Virgin Mary. The day commemorates the historic Battle of Covadonga, where Christian forces led by Pelagius achieved a significant victory against the Moors, marking the beginning of the Reconquista. Celebrations include solemn services at the Basílica de Santa María la Real de Covadonga and the Cathedral of San Salvador in Oviedo, alongside street fairs, parties, concerts, and sports competitions. The holiday reflects Asturias' rich cultural heritage and its historical significance in Spanish history.
