Crustumerium (or Crustumium) was an ancient town of Latium, on the edge of the Sabine territory, near the headwaters of the Allia, not far from the Tiber.
[1] In the legends concerning Rome's early history, the Crustumini were amongst the peoples which attended Romulus' festival of Neptune Equester.
[4] Livy records that in 468 BC the Sabines marched through the territory of Crustumerium towards Latium, ravaging the countryside.
[5] Pliny mentions it among the lost cities of Latium, but the name clung to the district, the fertility of which remained famous.
[4] The site of Crustumerium has been identified in the locality Marcigliana Vecchia, north to modern Rome along the Via Salaria, not far from Settebagni; only partially excavated, it covered an area of some 60 hectares.
