Oviedo (;
Asturian:
Uviéu) is the capital city of the Principality of
Asturias in northern
Spain and the administrative and commercial centre of the region. It is also the name of the municipality that contains the city. Oviedo is located approximately south of neighbouring cities
Gijón and
Avilés, which lie on the shoreline of the
Bay of Biscay; its proximity to the ocean causes Oviedo to have a maritime climate, in spite of it not being located on the shoreline itself.
