Llanes is a municipality of the province of Asturias, in northern Spain. Stretching for about 30 km along the coast at the extreme east of the province, Llanes is bounded to the south by the high ridge of the limestone Sierra del Cuera, which rises to over 1,100 m. The region is part of the Costa Verde of Spain, which is known for its spectacular coastal scenery, with 32 white sand beaches, and mountains covered with a deep green mantle. Llanes lies to the north of the Picos de Europa, a mountain range whose geology is almost entirely of limestone karst.

Asturian is a West Iberian Romance language spoken in the Principality of Asturias, Spain. Asturian is part of a wider linguistic group, the Asturleonese languages. The number of speakers is estimated at 100,000 (native) and 450,000. The dialects of the Astur-Leonese language family are traditionally classified in three groups: Western, Central, and Eastern. For historical and demographic reasons, the standard is based on Central Asturian. Asturian has a distinct grammar, dictionary, and orthography. It is regulated by the Academy of the Asturian Language. Although it is not an official language of Spain it is protected under the Statute of Autonomy of Asturias and is an elective language in schools. For much of its history, the language has been ignored or "subjected to repeated challenges to its status as a language variety" due to its lack of official status.
