About
Ostia Antica (lit. 'Ancient Ostia') is an ancient Roman city and the port of Rome located at the mouth of the Tiber. It is near modern Ostia, 25 km (16 mi) southwest of Rome. Due to silting and the invasion of sand, the site now lies 3 km (2 mi) from the sea. The name Ostia (the plural of ostium) derives from Latin os 'mouth'. Ostia is now a large archaeological site noted for the excellent preservation of its ancient buildings, magnificent frescoes and impressive mosaics. The city's decline after antiquity led to harbor deterioration, marshy conditions, and reduced population. Sand dunes covering the site aided its preservation. Its remains provide insights into a city of commercial importance. As in Pompeii, Ostia's ruins provide details about Roman urbanism that are not accessible within the city of Rome itself.
