After winning a competition commissioned by the Melbourne City Council in May 1978, the 'Vault' created by Ron Robertson-Swann, was considered by some to be too modern and unsympathetic for the Melbourne City Square location when it was installed in 1980. With media pressure, the decision was made to move the controversial sculpture to Batman Park. In 2002 it was then moved to the forecourt of the Australian Centre for Contemporary Art, corner of Grant and Dodds Street, in Southbank.
Flat sheets of prefabricated steel create a kaleidoscope of geometric forms and there is a sense of lightness to its assembly, evoking a paper-like origami shape. The yellow coloured abstract sculpture contrasts boldly against the rusty reddish-brown shades of the AACM building and seems contented with its current home.
