Old Treasury Building

John James Clark, 1858-1862


One of Australia’s finest 19th-century buildings, the Old Treasury Building’s construction between 1858 and 1862 was symbolic of the city’s rapid development. The design by the 19-year-old architect JJ Clark is in the Renaissance Revival style, derived from the 'Italian palazzo' form. The recently restored terraces and lamps were constructed in 1867.
