Opened in January 1968, Teatru Astra is an integral part of the larger musical organization, Soċjetà Filarmonika La Stella. Over the years, the theatre has hosted renowned international performers such as Raffaella Carrà, The Goggi Sisters, Al Bano and Romina Power, The Platters, Bobby Solo, Osibisa, the Montparnasse Ballet Troupe, as well as more recent acts like Nek, Amedeo Minghi, and the Ballet Classique de Paris. Besides world-class international stars, the management of the theatre has also actively supported and promoted local talent.

Featuring a seating capacity of approximately 1200, the venue offers two tiers of boxes flanking the theater, accompanied by a central balcony. The opulent red interiors, refurbished in 2005 post a 2003 fire incident, provide a welcoming ambiance.

Teatru Astra has earned praise for bringing a diverse range of performances to the Gozitan public, including operettas like Merry Widow, Principessa Della Czardas, The Goldoliers, The Great Waltz, Geisha, and others. The stage has also witnessed the presentation of works by literary giants such as Shakespeare, Goldoni, Ibsen, and Moliére.
