The Gralheira lode in the territorium metallorum Tresminas/Jales. A "treasure trove" of ancient mining technology
Frankfurter elektronische Rundschau zur Altertumskunde(2023)
Abstract
The little-known Roman gold mining site "Gralheira" is located near the well-explored mine of Tresminas. The 2.5 km long, almost dead straight archaeological monument from the first and second centuries AD is currently under threat from possible mining activities on the one hand and from modern waste disposal in the pits on the other. Since 2019, the Roman mining traces have been investigated by means of intensive field inspections, terrestrial 3d laser scanning and aerial photography. The following article will present first impressions and findings on this structure, as well as questions and preliminary interpretations.
