Roman Theatre of Amiternum, Roman theatre site in L'Aquila, Italy.

The Roman Theatre of Amiternum stands near San Vittorino in L'Aquila, built in the Augustan age using opus reticulatum masonry still visible on the walls. Its cavea, cut into the slope of Colle San Vittorino, measures 80 metres across and originally held about 2,000 spectators on two tiers. The lower section, with 18 rows reached by 3 radial stairways, is partly excavated and seats around 400. Opposite, across the curtain channel, lie the remains of a stage nearly 60 metres long.

The theatre was constructed in ancient times and served the city of Amiternum as an entertainment venue for its residents. Its creation reflects the Roman tradition of building theatres as central features in urban settlements.

The theatre served as a gathering place where the community experienced drama and entertainment together as part of their social life. The stone structure shows how Romans designed public spaces for shared moments.

The site is accessible by foot through marked pathways and visitors can walk among the ruins. It helps to wear sturdy shoes since the ground can be uneven, and there is limited shade in places.

Excavations in 1878 brought the theatre to light; it was declared a national monument in 1902 and restored in the 1960s and 1970s. Friezes and columns found during the digs are kept nearby, still waiting to join the collections of the Museo nazionale d'Abruzzo and the Museo archeologico di Santa Maria dei Raccomandati.
