Asturias has a rich artistic legacy that emphasizes Romanesque (Asturias Arts) indigenous architecture with monuments like Santa María del Naranco, Santa Cristina de Lena and San Miguel de Lillo. These monuments have a Ramirense Romanesque style (due to Ramiro I) or San Julián de los Prados, known as Santullano (Oviedo) of the Alfonsino pre-Romanesque style (due to Alfonso II), which are all in Oviedo. Other examples of architecture are Villaviciosa’s church, San Salvador de Valdediós (commonly known by the Asturians as “Conventín”), and the church of San Salvador de Priesca. Another example is Cabranes’ San Julian de Viñón.

The Romanesque style is very present, since all Asturias is crossed by one of the Camino de Santiago routes, which highlights the Monastery of San Pedro de Villanueva (near Cangas de Onis), the churches of San Esteban de Aramil (Siero), San Juan de Amandi (Villaviciosa) and Santa María de Junco (Ribadesella).

The Gothic style is not as abundant, but there are good examples of this style, such as the Cathedral of San Salvador in Oviedo.

The Baroque style is more present by means of palace architecture, with such notable examples as the Palace of Camposagrado and Velarde – the latter seat of Museum of Fine Arts of Asturias. The Baroque style stands out in public civil engineering and bridge tolls (Olloniego); the milestones, the chairs or seats present along the road to Madrid and the resort of Caldas de Priorio (Oviedo) building.

In 1985, the UNESCO declared the pre-Romanesque monuments and the Cathedral of Oviedo as World Heritage Sites.

In popular architecture, the traditional granaries in Asturias, called hórreos, are known for their demographic extension and their functional evolution, its basic characteristic being its mobility: it can be easily dismounted and transported to another location. The Panera is the evolution of the hórreo, with examples exceeding 100 square metres (1,076 square feet) of area covered. The purpose of the horreo is to store objects and crops. With the arrival of maize and the beans, they were endowed with exterior corridors and railings for drying the harvests.

Asturias is home to the only architectural work in Spain (as well as the largest in Europe) of the Brazilian architect and disciple of Le Corbusier; Oscar Niemeyer: the Oscar Niemeyer International Cultural Centre. The architectural project was donated to the Principality by the architect, who was awarded the Prince of Asturias Award for the Arts, in the XXV edition of these awards. Niemeyer’s project combined several different elements, and projected an open space, a place for education, culture and peace.

In the capital of the Principality stands one of the most representative buildings of modern architecture, the Palace of Congresses of Oviedo, by the Spanish architect Santiago Calatrava, who also awarded the Prince of Asturias of Award for the Arts in 1999.

Special importance has been placed in recent years on the recovery of industrial heritage through various routes and industrial museums, especially in the central area of the region.
