Over the course of a week, Pedro Miró, Otto Lowe, Ferdinand Saumarez Smith and Gabriel Coleman carried out a high-resolution recording of all the four funerary chambers, which are organised over two levels. Chamber A, B and C were recorded using LiDAR, photogrammetry and a portable version of the Selene Photometric Stereo Scanner; Chamber D was recorded with LiDAR. While the chambers share similar structural layouts, their decoration differs in their vibrant polychrome trompe-l’œil effects that imitate architectural details and luxurious furnishings.

Tomb C in the Ipogeo dei Cristallini in Naples is possibly the best preserved Greek tomb known today. The highlight of the tomb is the polychrome head of Medusa. As access to the tomb is not possible for visitors with limited mobility, a facsimile—alongside physical and virtual models—will soon be installed at the entrance of this ancient underground burial complex in the Rione Sanità. The project has been made possible by a grant from the Regione Campania and reflects a longstanding commitment to making heritage accessible to everyone.

The funerary chambers of the Ipogeo dei Cristallini are believed to be contemporary with the tomb attributed to Philip II in Vergina. The digital data has been incorporated into the conservation records managed by the Soprintendenza Archeologica, Belle Arti e Paesaggio per il Comune di Napoli, in collaboration with the Central Institute for Restoration of Rome (ICR), supporting both the long-term preservation and wider dissemination of the Ipogeo.
