Lavinium

Lavinium was a port city of Latium, 53 km (33 mi) to the south of Rome, at a median distance between the Tiber river at Ostia and Anzio. The coastline then, as now, was a long strip of beach. Lavinium was on a hill at the southernmost edge of the Silva Laurentina, a dense laurel forest, and the northernmost edge of the Pontine Marshes, a vast malarial tract of wetlands. The basis for the port, the only one between Ostia and Anzio, was evidently the mouth of the Numicus or Numicius river. The Alban hills loom in the background.
