Roman Theatre of Ostia

The Roman Theatre of Ostia was a performance building with a semicircular orchestra, marble floors, and sixteen shops arranged through arches along the main facade facing Decumanus Maximus. The structure displays the typical features of Roman theatre architecture with multiple levels for different spectators.

The theatre was built around 13 AD under Emperor Augustus and originally seated about 2,500 spectators. By the end of the second century, it had expanded to hold up to 4,000 people.

The decorative elements throughout the structure reveal how performances were staged, with stucco work adorning the corridors and columned niches framing the stage. Walking through, you can see how the design guided spectators' attention toward the theatrical action.

The excavation site can be visited during regular opening hours as part of the larger Ostia Antica Archaeological Park. Visitors should expect uneven ground and wear comfortable shoes, as there is considerable walking involved.

The orchestra area contained mechanisms that allowed water-based performances, transforming the space into a venue for aquatic displays. This technical sophistication reveals how Roman engineers created spectacular entertainment options.
