The Stone Tidal Fish Weirs of the Mol`ene Archipelago, Iroise Sea, Brittany, Western France: a long-term tradition with early megalithic origins
Résumé
This reports on a project that combined evidence gleaned from aerial photographs, place-names, interviews, topography, LIDAR data, and sonar bathymetry to locate stone tidal fish weirs in the Mol`ene Archipelago. The results were verified by diver and pedestrian visual surveys. Models of Holocene sea-level change allowed a group of possibly Late Mesolithic–Early Neolithic weirs to be recognized, with a second group broadly dated to the later Neolithic–Early Bronze Age. The construction of these long megalithic structures is compared to the funerary monuments for which the Mol`ene Archipelago is well known, in terms of technique, cost, and societal organization.
