The Old Treasury Building is considered one of the finest public buildings in Australia and occupies a unique position in Melbourne's history, having had its origins in the 1850s Victorian Gold Rush which accelerated the city's development.
The exterior of the building is finished in Bacchus Marsh sandstone on bluestone foundations. When the State Treasurer and his officers moved to the State Government Offices at Treasury Place in 1878, the building was renamed the Old Treasury.
It now houses the Melbourne City Museum.
