Teatru Astra in Victoria, Gozo was inaugurated in January 1968. It forms part of a larger musical voluntary organisation, the Soċjetà Filarmonika La Stella, founded in 1863. During these years the theatre has hosted international performers such as Raffaella Carrà, The Goggi Sisters, Al Bano and Romina Power, The Platters, Bobby Solo, Osibisa, the Montparnasse Ballet Troupe and more recently, Nek, Amedeo Minghi and the Ballet Classique de Paris. Local talent has been extensively put to use and encouraged by the Theatre.

To Teatru Astra's credit, the Gozitan public enjoyed operettas such as Merry Widow, Principessa Della Czardas, The Goldoliers, The Great Waltz, Geisha and many others. Works of literary giants including Shakespeare, Goldoni, Ibsen, and Moliére were also presented on the Teatru Astra stage.

In 1978, Teatru Astra ventured in the greatest form of stage production: the Opera. Rigoletto was first on the list. This was successfully followed by Il Barbiere di Siviglia, Aida, Lucia di Lammermoor, L'Elisir d'Amore, Norma, La Traviata, La Forza del Destino, Nabucco, Turandot, Il Trovatore, Macbeth, again Rigoletto (1998) and Aida (1999), La Gioconda and many others. In more recent years Teatru Astra produced Suor Angelica, Cavalleria Rusticana, Pagliacci, Macbeth, Turandot, Rigoletto, La Traviata, Norma, Madama Butterfly, Otello, Nabucco, La Bohème, Aida and last year Lucia di Lammermoor.

Teatru Astra patrons have been exposed to world-class singers direct from the Metropolitan Theatre in New York, Teatro alla Scala and Sofia State Opera House amongst whom Ghena Dimitrova, Pamela Kucenic, Adelaide Negri, Francesca Patane, Joseph Calleja, Nicola Rossi-Lemeni, Aldo Protti, Mark Rucker, Rumen Doikov, Daniela Dessì and Giuseppe Giacomini feature prominently. The Teatru Astra stage has also been the venue from where internationally acclaimed local artistes, including Miriam Cauchi and Joseph Calleja, debuted their operatic career.

Festival Mediterranea, now in its seventeenth edition, is an initiative of Teatru Astra which is being marketed internationally. Teatru Astra has been refurbished in 2005 after an extensive fire which broke out on 8 November 2003.

In April 2016, Teatru Astra successfully ventured into the musical genre, with Grease, followed by the record breaking productions of Evita and Jesus Christ Superstar. The last two titles have been performed three times during March 2017 and March/April 2018 respectively. In November 2016 Teatru Astra launched the Astra School of Musical Theatre (ASMT).
