Victorian Trades Hall is the home of the Victorian Trades Hall Council. It is located on the corner of Lygon Street and Victoria Street, just north of the Melbourne central business district, in the suburb of Carlton, Melbourne, Victoria, Australia. It is the world's oldest trade union building.
In 1856 the Melbourne Trades Hall Committee was formed and received a grant of land to build the Melbourne Trades Hall. The original Trades Hall was opened in May 1859, built by workers as an organising place for the labour movement in Melbourne. The workers financed the construction of the building themselves. It was built in the style of the parliament buildings which were just down the road, and over the years has been further developed. The Hall underwent an upgrade from 1874 to 1925 at the hands of architectural firm Reed & Barnes. With increasing activity during the 1880s in the Australian labour movement, the committee became a Council to reflect its expanding role, though the full title, Victorian Trades Hall Council was only formally adopted in 1968. The building remains one of the most historically important sites in Melbourne today, being classified by the National Trust and included in the Register of Historic Buildings (Victoria).
The Trades Hall is located across the road from the eight-hour day monument which was erected to honour the Victorian workers who won the first 8-hour working day in the world in 1856. It is the birthplace of organisations like the Victorian Labor Party and the Australian Council of Trade Unions. Four flags fly from the roof of the building: the Australian Flag, the Eureka Flag, the Australian Aboriginal flag, and the red flag.
