Ostia Antica is a large archeological site, close to the modern town of Ostia, that was the location of the harbour city of ancient Rome, which is approximately 30 km to the northeast. "Ostia" in Latin means "mouth". At the mouth of the River Tiber, Ostia was Rome's seaport, but, due to silting and a drop in sea level, the site now lies 3 km from the sea. The site is noted for the excellent preservation of its ancient buildings, magnificent frescoes and impressive mosaics.
