Oviedo, the capital of Asturias in northern Spain, offers a rare mix of medieval heritage and everyday life that feels rooted rather than staged. The city’s historic center is home to some of the oldest pre-Romanesque buildings in Europe, including the UNESCO-listed Santa María del Naranco and San Miguel de Lillo. Cider, not wine, defines the local table. Oviedo is surrounded by apple orchards, and the traditional drink, sidra natural, is poured from a height by skilled escanciadores.
