Identified beneath the stables of Villa Torlonia in 1918, the catacomb extends over two levels at different depths, originally independent and later connected. It had two entrances on a side branch of the Via Nomentana (now Via Spallanzani); so far, only the western one has been used: a staircase cut into the rock leading to the lower and older sector.
The upper area contains the most important burials – cubicula and arcosolia decorated with architectural elements and frescoes dated between 320 and 340 CE. Throughout the catacomb, several thousand tombs have been identified, some still sealed, along with around one hundred inscriptions in Greek, Latin, and Hebrew. Fragments of glass and pottery have also been found.
The catacomb is currently not open to visitors, as it has been undergoing restoration work since 2017.
