The German–Icelandic cooperative project “Storytelling at the Edge of Civilisation” was funded by the German Research Foundation (DFG) from 2023 to 2026 (project number 495416732); it was a cooperation between the Institute of Scandinavian Studies of Goethe-University in Frankfurt am Main, the Institute of Nordic Philology of LMU Munich, the IT-Group Humanities of LMU Munich and the Research Centre of the University of Iceland in Strandir – The Folklore Institute. Its aim was to map, contextualise, and analyse landscape-related storytelling traditions in the districts of Árneshreppur and Kaldrananeshreppur in the Strandir region of the Icelandic Westfjords. To this end, both folktale collections and archival materials were examined, and fieldwork, including original interviews, was conducted. As part of the project, an interactive map was developed in which narrative sites are recorded with GPS coordinates, photographs, descriptions, and excerpts of stories, interconnected with one another, and filterable by narrative motifs (such as elves, trolls, or burial mounds). The project website is available at: https://www.strandasogur.gwi.uni-muenchen.de/ For long-term preservation, the research data produced within the project are archived via Open Data LMU. The dataset comprises two structurally identical JSON files containing georeferenced narrative sites and associated structured metadata. In addition, two ZIP archives containing the corresponding photographic documentation and the project bibliography are included. Parts of the dataset are not publicly accessible for reasons of research ethics. This restricted data is structural identically published as encrypted supplement to the present dataset: https://doi.org/10.5282/ubm/data.799.
