Ostia

an ancient Roman colony, commercial harbor, and naval port, located at the mouth of the Tiber River.

Remains of the oldest fortifications date from the mid-fourth century B.C. The port was rebuilt at the beginning of the empire; intensive construction was conducted under Trajan. Surrounding the port were warehouses, trading establishments, and apartment blocks.

Excavations conducted since the end of the 18th century have unearthed temples (Capitolium and others), a theater, public baths, multistory dwellings, and other structures. Ostia was known for its saltworks. The port fell into decline after the capital was transferred from Rome to Constantinople (330 A.D.), but even during the Middle Ages it maintained its strategic naval importance.
