San Roque de Riomiera
From the town of La Concha to Portillo de Lunada, the municipality is one of the best examples of glacier valley in the region. The ice abrasion leave residues in lower altitudes (600 m.). High Miera contrasts due to its glacier circus, moraines, rounded and filed material deposits and riverbeds with the rough river profile down from La Concha.
- Archaeological heritage: Covallarco and Cascajosas caves are the main archaeological features in San Roque de Riomera. Covallarco has an old lime furnace and a enclosed structure, a well as bone remains and lithium that prove their prehistoric origins.
- Religious architecture: while being a simple temple from 16th century, the church of San Roque in La Pedrosa is outstanding, as well as the Chapel of Our Lady de los Dolores in Merilla an interesting sanctuary of large dimension built in masonry and covered with lozenge tiles.
- Pas cottage: in Merilla and La Concha there are examples of Pas cottages dating from 17th to 19th centuries. In Bernallán, La Brena, El Coburco, La Lunada and El Toral. The pattern is a rectangular building with two storeys. The top one, the “payo”, is used for grass storage, and the lower one is for stabling. It is built with local materials, such as wooden trusses and irregular masonry. The roof is made of lozenge tiles.
- Industrial heritage: an invaluable Modern Age building, the Resbaladero de Lunada is the most striking icon of industrial heritage in the area. Large scale construction work took place during 18th century and early 19th century due its building, included a masonry sluice in La Concha and the trunk slide built in 1791, located next to the entrance to Lunada. It’s base was almost one kilometre (now disappeared in some parts), above which there was a wooden channel. Its goal was to speed up trunk transportation from higher places. At its feet there was “casa del Rey”, a storage and service building for the slide workers. The slide was included in 2003 in the General Inventory of Cultural Heritage of Cantabria.
