Between 1953 and 1975, the deserted medieval town of Borgund became the site of Norway’s most extensive excavations of ordinary people's settlements outside the country’s surviving towns. Initially undertaken as rescue excavations, the investigations soon evolved into a research-driven enterprise. The paper examines the background to the excavations and explores why, despite considerable academic and public interest, their results attracted relatively little scholarly attention in subsequent decades. The Borgund Kaupang Project is briefly presented as a case study demonstrating how a major archaeological legacy dataset can be revitalised for new research.
