In Miera there still are bridges from centuries 16th and 17th to cross Miera river and its streams, engineering fundamental works to keep communication and allow commercial interchange between towns in the region. Puente Mayor in Liérganes or “Puente Romano” (Roman Bridge) is the most famous of them due to its strategical value. This Roman bridge connects Transmiera with Asturias de Santillana and with Camino de Castilla, to Portillo de Lunada. It has two rounded archs of unequal size and cutwaters with spindle form. It was stone built on the river and has been preserved in a perfect state since its construction without needed big restoration. Next to it, there is a well-kept mill from 1667.
- Hydraulic inventions: scattered all through the municipality there are bridges, mills and dams, the basic elements of Modern Age rural economy. The outstand Puente Mayor de Liérganes, that of La Costera, Rubalcaba and Los Carros in Pánames. The best preserved mills are the one next to Puente Mayor and the two in Casa del Ángel, in Los Prados. There are other mills and dams in the neighborhoods to Calgar and Bucarrero, in Pánames.
- Historical and artistic ensemble: Liérganes is a place of great richness on its streets. Manor houses, palaces, churches and chapels show an age in which this town was an important socio-economic center. In civil architecture (16th to 19th c.), outstanding are the Houses of Rañada-Rubalcaba, of Intendente Riaño, of Langre, of Setién, of El Acebo, the Manor House of Cárcoba-Rubalcaba and the Palace of La Rañada. In religious architecture of the Church of Saint Peter ad vincula (16th-17th c.), the Church of Saint Sebastian (14th-15th c.), the Chapel of El Carmen and of Saint Francis (19th c.) and the Shrine of El Cristo del Humilladero (16th c.) are all notable.
- Movable heritage: the Palace of Elsedo in Pámanes guards an important contemporary art collection. It is composed by more than a hundred pieces from Spanish or Spain-linked artists, distributed between the garden and the residence rooms.
- Route through the neighbourhoods in Liérganes (6 Km.): a beautiful walk around urban centre of Liérganes town, one of the best civil architectural groupings in Cantabria.
- Hiking between Rubalcaba-La Isla (2,5 Km): not too difficult a route that goes along the Miera riverside, between remnants of local forest and 16th century bridges.
- Trekking to “Tetas” in Liérganes” (9 Km): this route that starts in Barrio del Mercadillo has a medium difficulty and a 400 metres slope. From the top of Cotillamón and Marimón one can enjoy a great panoramic view: the central coast of Cantabria to the north, and the rough calcareous reliefs of high Miera to the south.
