Lavinium, Pomezia

Lavinium was a port city of Latium, 6 km to the south of Rome, midway between the Tiber river at Ostia and Antium. 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 Antium, was evidently the mouth of the Numicus river. ()
