Brisbane City Hall, in Brisbane, Queensland, Australia, is the seat of the Brisbane City Council. It is located adjacent to King George Square, where the rectangular City Hall has its main entrance. The City Hall also has frontages and entrances in both Ann Street and Adelaide Street. The building is considered one of Brisbane’s finest and is registered on the Register of the National Estate since 1978.
The building has been used for royal receptions, pageants, orchestral concerts, civic greetings, flower shows, school graduations and political meetings.
In 2009, it was discovered that the building suffered from severe structural problems. After a three-year restoration, the building was re-opened on 6 April 2013…
The centre of City Hall features a stunning auditorium, based on the Pantheon, Rome, and several smaller reception rooms. The auditorium is a large circular hall that can seat up to 2,500 people and is covered by a large copper dome. Beneath this dome there are 8,500 L.E.D lights that display a light show. 
Following the 2010-2012 redevelopment, City Hall’s role is primarily to support public gatherings. In addition to the main auditorium, reception rooms that had been converted to administration spaces over the years have been restored to their original purpose. An industrial kitchen installed in the basement during the renovations provides catering support for events; previously external caterers had to be used.
The Museum of Brisbane is now relocated into a purpose-built facility on the rooftop. In addition to a changing program of exhibitions, the museum also operates tours of the building and tours of the clock tower.
There are two privately operated cafes in City Hall, the Red Cross Cafe and the Shingle Inn. The Shingle Inn cafe was originally not part of City Hall but was located in Edward Street and was demolished as part of the Queen’s Plaza development. However, the iconic interior fittings of the Shingle Inn Cafe were removed and put into storage, allowing it to be reconstructed within the City Hall.
The only administrative functions remaining in the city hall are the suite of offices for the Lord Mayor and Deputy Lord Mayor.
