Spoken in the remote forest region of Älvdalen - a place thick with forest and steep valleys - Elfdalian used to be the main language of the area, but Swedish has increasingly become dominant and few young people speak it today.
In this slow radio edit, we hear a collage of forest sounds and local voices, travelling through Älvdalen, exploring some of the mysteries of the language and its links to Sweden's ancient, Viking past.
