The Bakery of Silvano supplied the local population and exported bread to Rome, highlighting its significant role in the ancient economy.

The Theatre

The Theatre in Ancient Ostia is an impressive structure built during the reign of Augustus in the late 1st century BC. Expanded in the 2nd century AD, it could accommodate up to 4,000 spectators. The semi-circular seating arrangement and well-preserved stage area reflect the grandeur of Roman entertainment architecture. The lowest rows, made of marble, were reserved for high-status individuals. Behind the stage, the scaenae frons, or decorative backdrop, featured three marble theatrical masks. Today, the theatre is still used for cultural events, allowing you to experience the vibrant atmosphere of ancient performances.

The Piazza of the Corporations

The Piazza of the Corporations in Ostia Antica was the city's bustling commercial centre. This large square, situated behind the theatre, was surrounded by offices of various trade guilds. Each office was decorated with mosaics depicting their trade, such as grain importers, shipbuilders, and rope-makers. Statues of prominent citizens and corporation leaders adorned the square. In the centre, a 1st-century AD temple likely dedicated to Ceres, the goddess of agriculture, underscored the importance of grain trade. The Piazza of the Corporations provides a vivid insight into ancient Ostia's economic life and commercial activities.

History of Ostia Antica

Ancient Ostia was founded in the 7th century BCE by Rome's fourth king, Ancus Marcius. It started as a small settlement used primarily for salt production but quickly grew due to its strategic location at the mouth of the Tiber River. This made it a crucial naval base during the Punic Wars. The construction of a fort in the mid-4th century BCE further emphasised its importance in protecting Rome’s coastline. As Rome expanded, Ancient Ostia became the main port, facilitating trade and supplying grain to the capital. It thrived as a commercial hub, with warehouses, shops, and temples emerging to support its bustling population.

The city's prosperity peaked in the 2nd century CE, boasting a population of around 50,000. Ostia's decline began in the 3rd century due to economic troubles and increasing pirate attacks. The construction of the new port, Portus, by Emperor Claudius also shifted maritime activities away from Ostia. Over time, the city faced further decline from barbarian invasions and malaria outbreaks. By the 9th century, it was largely abandoned. Excavations in the 19th and 20th centuries have uncovered a well-preserved city, offering a fascinating glimpse into the daily life and architecture of ancient Rome. Today, Ostia Antica stands as a testament to Rome’s rich historical tapestry.
