Teatro Traiano, Municipal theatre in Civitavecchia, Italy.

Teatro Traiano is a theatre located in central Civitavecchia featuring classical Italian architecture and 638 seats arranged across multiple levels. The building displays typical 19th-century design elements that define the character of the surrounding square.

The theatre opened in 1844, establishing the beginning of a continuous theatrical tradition in this Mediterranean port city. Since then, the venue has hosted hundreds of productions and events that shaped local entertainment.

The venue hosts theatrical productions, film screenings, and performing arts events throughout the year, serving as a gathering place for the local community. These performances shape the cultural rhythm of daily life in this port city.

The theatre stands between Corso Centocelle to the south, Largo Plebiscito to the west and Via Traiana to the north, facing the 18th-century Palazzo del Quartierone, now the Guardia di Finanza headquarters. The foyer and cloakroom are available; there is no bar. The house holds 638 seats: 384 in the stalls, 206 in the gallery and 48 in the loggione.

The painted foyer vault lists Verdi, Puccini, Rossini and Donizetti, who conducted at the Traiano; Caruso, Callas, Pavarotti, Fracci and Taglioni also performed here. The theatre's 19th-century curtain by Vincenzo Podesti, showing Trajan sacrificing to Neptune during the building of the port, survived the war but was lost afterwards.
