Historical Background

The theatre was built between the end of the 1st century BC and the beginning of the 2nd century AD. The first phase dates to the Augustan age, and a major restoration was later funded by Quintus Petronius Modestus, procurator of Trajan, as attested by the inscriptions on Aurisina stone. During the Middle Ages, the theatre disappeared beneath houses, but the toponym ‘Rena vecia’ preserved its memory. In 1814, architect Pietro Nobile identified it, but it was only in 1938, after demolishing the neighborhood, that it was brought to light. Today it is a symbol of Roman Trieste.

Architecture and Materials

The structure is built in masonry, with the cavea (seating area) leaning against the hill. There were 14 lower rows, of which 12 remain, and possibly 7 upper rows made of wood. The orchestra is semicircular, and the scena was a monumental façade with niches for statues. What about the materials? Aurisina stone, a light gray limestone, was used for columns and decorations. The stage was clad in slabs of red marble with plant motifs. A semicircular wall with holes supported a wooden covering. Walking among the ruins, you notice the attention to detail: every stone tells of the skill of Roman architects.

The Statues and Inscriptions

During the excavations, numerous marble statues were discovered, now displayed at the J.J. Winckelmann Museum of Antiquities (near San Giusto). They depict deities: Asclepius, Hygieia, Minerva, Apollo, Bacchus, and Venus. There is also a drunken Silenus used as a fountain. These sculptures, copies of Greek models from the 4th century BC, decorated the stage and the backdrop. The inscriptions on Aurisina stone commemorate the patron Quintus Petronius Modestus. One of the richest sculptural cycles in Italy: it’s worth visiting the museum to see them.

Why Visit It

1. One of a kind: It is one of the few Roman theaters built right by the sea (even though the seafront has since receded). 2. Free and central: You can see it from Via del Teatro Romano without a ticket. Perfect for a stop during a stroll in the city center. 3. Magical atmosphere: At sunset, the warm light on the ancient stones creates an exciting spectacle. Even if closed for renovations, the view from outside is already rewarding.

When to Go

The best time? Late afternoon, when the sun lights up the cavea and the hill’s shadow creates a striking contrast. In summer, the evenings are pleasant: sometimes the theater hosts performances (if open). In autumn, the golden light on the leaves of the nearby park adds charm. Avoid the midday hours in summer: the heat is felt. But honestly, every season has its charm.

💡 Did You Know…?

It is said that during the excavations of 1938, workers found a perfectly preserved statue of Apollo, which seemed to observe the work. Today, the sculpture, displayed at the Winckelmann Museum, is considered the ‘guardian’ of the theatre, and many visitors swear that its gaze follows those who walk among the ruins.
