Ostia Antica Archaeological Park Rome

The excavations at Ostia Antica outside Rome constitute the biggest archeological site in the Lazio region. Better preserved than Pompeii, the ruins of this ancient port at the mouth of the river Tiber provide an invaluable insight into the way the Romans used to live in the heyday of the Empire.

History and description

Rome - Ostia Antica - Cardine Massimo
What used to be the main street of Ostia Antica.

Ostia might have already existed in the 7th century BC, but what is certain is that a Roman castrum protecting the river mouth and the Etruscan salt mines at nearby Maccarese was constructed in the 4th century BC. This military stronghold developed into a commercial harbor, from where goods arriving by sea were transported to Rome itself.

In those days Ostia was a flourishing city with around 100 thousand inhabitants. Huge ships from all over the Mediterranean dropped their wares at Ostia. From here they were shipped to Rome by means of flat barges, the river Tiber not being very deep.

Ostia was at its most powerful during the reign of the emperors Claudius and Trajan and remained an important port until the end of the 5th century, when the Barbarians attacked Rome.

After that the ancient city was abandoned and forgotten, until in the 19th century the Pope ordered excavations. In the early 20th century, Mussolini had an even bigger part dug up.

The well-preserved ruins include temples, baths, theaters and even a huge business complex.

What to see

Piazzale delle Corporazioni: A huge square with more than 70 corporations. The mosaics give an idea of the nature of each business.

Theater: One of the oldest buildings in Ostia Antica and once the background to performances of classical Greek drama. Nowadays, during the summer months, still used for its original purpose.

Ostia Forum: With a temple for the Gods Minerva, Jupiter and Juno. Several of its ancient columns are still standing.

Casa Diana: An apartment complex, built around a central courtyard.

Thermopolium: Thermopolium means “sale of hot drinks”, hence a cafe.
