Located at the springs of the Dieue river, Sommedieue was already populated during the Gallo-Roman era, as shown by recently uncovered archeological remains. Until the 18th century, Sommedieue remained a small community of lumberjacks and charcoal makers. During the 19th century the village became industrialized as it acquired a grinding mill, a sawmill, woodturning mills, and chairs and furniture manufacturers. Toward the end of the 19th century, Sommedieue had ca. 300 workers. Most of these activities have now faded away.
