The monastery of Santo Toribio de Liébana is located in the municipality of Camaleño, in one of the Viorna hill´s foldings. It´s foundation could have been due to the work of Santo Toribio, the monk, native from Turieno, who was a preacher in the region of Palencia during the VI century and retired to the mountains of Liébana with a group of companions.In 828 the monastery appears quoted, for the first time in a document, under the primitive name of San Martín. In 915 eighteen monks lived in community. The first written evidence of the name change from San Martín to Santo Toribio appears in the year 1125. Its worship could very well have started as a result of the transfer in the body of the Saint Bishop of Astorga (León). At the end of the XII century the monastery changes to priory, depending on San Salvador de Oña, and it´s in the year 1256 when the gothic church, which can be contemplated today, is built; that is, restoring the remains of the older romanesque one.
