Abstract

The ISPC-CNR is conducting research activities aimed at identifying ancient quarries that supplied the public building sites in the Athenaion of Castro, where excavations revealed dry-stone city walls made of calcarenite blocks and built in three phases between the 4th and 2nd cent. BC. The paper is focused on the large coastal quarries of Porto Miggiano, located approximately 4.5 km NE of Castro, where the extraction was carried out in function of sea transportation of the blocks. The extraction sites were documented through laser scanning and photogrammetry by a drone. In the main quarry, which covers an area of approximately 0.4 hectares, thanks to the metrological analysis of the stepped faces, four extraction areas were identified corresponding to at least five cultivation phases. The oldest and most extensive one affects the central sector of the quarry, where large blocks compatible (for dimension and macroscopic aspect) with those of the third phase of the Castro city walls, dated to the beginning of the 2nd cent. BC, were extracted.
