Adelaide Festival Centre, Australia's first capital city multi-purpose arts centre and the home of South Australia's performing arts, was built in the 1970s, designed by Hassell Architects. Located on Kaurna Yarta, the Festival Theatre opened in June 1973 with the rest of the centre following soon after. The complex includes Festival Theatre, Dunstan Playhouse (formerly The Playhouse and Optima Playhouse), Space Theatre (formerly The Space) and several gallery and function spaces. Located approximately north of the corner of North Terrace and King William Road, lying near the banks of the River Torrens and adjacent to Elder Park, it is distinguished by its two white geometric dome roofs, and lies on a 45-degree angle to the city's grid. Adelaide Festival Centre hosts Adelaide Festival and presents major festivals across the year including Adelaide Cabaret Festival, OzAsia Festival, DreamBIG Children's Festival, Adelaide Guitar Festival and OUR MOB. It is also home to Adelaide Symphony Orchestra, State Opera South Australia, Australian Dance Theatre, State Theatre Company South Australia, The Australian Ballet, Brink and Windmill Theatre Co. The Festival Centre is managed by a statutory corporation, the Adelaide Festival Centre Trust, which is responsible for encouraging and facilitating artistic, cultural and performing arts activities, as well as maintaining and improving the building and facilities of the Adelaide Festival Centre complex and Her Majesty's Theatre. The Festival Centre was erected on the site of the Adelaide City Baths, which had been there for over a century. the site (external to the venues) is undergoing major redevelopment, started in 2016, but the theatre spaces have remained open. The car park has been completed. The redevelopment was completed in February 2022. In the 1960s, the Adelaide Festival of the Arts started to outgrow the city's existing venues, and there was a push to build a "Festival Hall". The Adelaide Festival Theatre Act 1964 provided for the erection of the Festival Theatre building.
