From: Hidden chamber discovery in the underground Hellenistic necropolis of Neapolis by muography

(a) Foreground top view of the studied site as seen with Google Maps 25. The dashed circle corresponds to the region explored in this paper by the muography technique with two detectors. (b) Schematic drawing of the underground level at the depth of 10 m with Greek funeral chambers numbered from 1 to 11. Scale and orientation in (a) and (b) are the same. Chambers 2 and 3 are unknown and their existence was hinted by the integrated site topology reconstructed with 3D surveys. (Satellite imagery: Google \(\copyright\)2022 Imagery date 7/29/2020).
