The Treasury Building, previously known as the New Public Offices, is a heritage-listed former public administration building located at 21 Queen Street in Brisbane, and is the largest 19th-century government building in Australia by gross floor area. It was built from 1886 to 1928 for the Queensland Government. On 21 October 1992 the Italian Renaissance building was added to the Queensland Heritage Register.
The building is located at North Quay, near the northern end of Victoria Bridge. Although officially fronting on Queen Street, the building occupies an entire city block surrounded by Queen Street, George Street, Elizabeth Street and William Street. The Elizabeth Street frontage is opposite the Queens Gardens. In the 1890s and early 1900s the imposing Treasury Building served as a symbol of self-government and as a focus for celebratory and patriotic displays.
