Asturias, officially the Principality of Asturias, is an autonomous community in north-west Spain. It is coextensive with the province of Asturias and contains some of the territory that was part of the larger Kingdom of Asturias in the Middle Ages. Divided into eight comarcas (counties), the autonomous community of Asturias is bordered by Cantabria to the east, by León (Castile and León) to the south, by Lugo (Galicia) to the west, and by the Bay of Biscay (Cantabrian sea) to the north. Asturias is situated in a mountainous setting with vast greenery and lush vegetation, making it part of Green Spain. The region has a maritime climate. It receives plenty of annual rainfall and little sunshine by Spanish standards and has very moderated seasons, most often averaging in the lower 20s celsius. Heat waves are rare due to mountains blocking southerly winds. Winters are very mild for the latitude, especially near sea level. The most important cities are the communal capital, Oviedo (Uviéu), the seaport and largest city Gijón (Xixón), and the industrial town of Avilés. Other municipalities in Asturias include Cangas de Onís (Cangues d'Onís), Cangas del Narcea, Gozón, Grado (Grau or Grao), Langreo (Llangréu), Llanera, Laviana (Llaviana), Lena (Ḷḷena), Llanes, Mieres, Siero, Valdés, Vegadeo (A Veiga), and Villaviciosa (see also List of municipalities and comarcas in Asturias). Asturias is also home of the Princess of Asturias Awards.
