The Sydney Opera House was completed in 1973, after fourteen years of construction. The architect, Joern Utzon, designed his expressionist masterpiece to feature a roof of 'sails', which include more than a million ceramic tiles. Sydney Opera House has five performance halls: the Grand Concert Hall, Opera Theatre, Drama Theatre, Playhouse and The Studio. It is a central space for many of the city's biggest performances and celebrations, and a hub of constant activity.
The Opera House stages around 3,000 performances per year of all types, which is an average of eight performances per day. These range from small free concerts to lavish operatic performances, and at any given time there are several performances occurring.
