The monastic church of San Juan of Berbio, the origins of which go back to the 11th Century, is situated on the outskirts of Infiesto. Today's church was restored in 1994 and conserves only the main, very simple facade and some cornice supports as Romanesque elements.
The church of San Pedro of Beloncio, of which there remains a barely decorated very late Romanesque side elevation, is situated at 4 km. from Infiesto.
Other churches in the municipality, such as those found in Qués, Cereceda, Sorribes, Lodeña, Borines and Espinaredo, have elements of greater or lesser architectonic interest. From the 20th Century there is the parish of San Antonio of Infiesto and the neo-baroque building of San Pedro of Villamayor.
There are several mansions and palaces dating from the 16th to the18th centuries dotted around nearly every parish of the municipality.The ‘Torre del Omedal' (Miyares), the ‘Torre de Lodeña', the ‘Palacio de Sorribas', the ‘Palaciode Cutre' (La Goleta), the ‘Palacio de Rubianes' (Cereceda) and the ‘Palacio de las Huelgas' (Villamayor) are outstanding examples.
There are also some examples of ‘indiana' architecture, brought by returning emigrants to the Americas, in Piloña.
The singularity of the park around the fish farm in El Orrin deserves special mention. Although nowadays in disuse, it was until a few decades ago a nursery of conifers, eucalyptus, and American oaks which supplied the whole of Asturias. Fir trees, cedars, white cedars, larches, spruces, Mexican weeping pines and other varieties of conifer were planted here over a century ago. This collection should constitute a small botanical garden, according to the Pialonia cultural group.
There are also many popular constructions in nearly every village, with the traditional long wooden balconies as the most obvious example. Espinaredo has a collection of ‘hórreos' and ‘paneras', typical granaries elevated on thick stilts or wooden pillars.
The medieval Jacobean route to Santiago de Compostela passed through Piloña, which today has a cultural society (Pialonia) and sports society (Vízcares Mountain Group) which contribute to festive and cultural activities throughout the year.
