Throught the Camino de Santiago, the pilgrim can find many religious monuments (churches, monasteries…), remains of the centuries of tradition and history originated in this route. Among them, however, the Monastery of San Millán de la Cogolla is special, since it holds the honor of being considered the birthplace of the Castilian language, the most spoken language in modern Spain.
The Monastery of Suso (one of the two existing monasteries in San Millán) was, in effect, the place where the “Glosas Emilianeses”, considered the first words written in Castilian (or at least a primitive version of it), were authored. These were notes written on the margin of latin codexes, in order to clarify words or expressions from the main text. Some of these comments were also written in a primitive version of the Basque language, so they can also be considered the oldest existing Basque text.
San Millán de la Cogolla was also the working place of Gonzalo de Berceo, considered the first literary writer in castillian. His main work, “Milagros de Nuestra Señora”, was a compilation of miracles attributed to the Virgin Mary written around 1260, and is considered as one of the first literary works written in Castilian.
Due to these reasons, the Monasteries of San Millán were declared World Heritage Sites by UNESCO in 1997.
