Santa María del Naranco and San Miguel de Lillo
These two churches—the first with superb views and its plainer sister 300 yards uphill—are the jewels of an early architectural style called Asturian pre-Romanesque, a more primitive, hulking, defensive line that preceded Romanesque architecture by nearly three centuries. Commissioned as part of a summer palace by King Ramiro I when Oviedo was the capital of Christian Spain, these masterpieces have survived for more than 1,000 years. Tickets for both sites are available in the church of Santa María del Naranco.
