This artwork by Otto Herbert Hajek is between the rear of South Australia’s Parliament House and the Adelaide Festival Centre.
It’s titled Adelaide Urban Iconography and was commissioned by the Adelaide Festival Centre Trust and opened by the Queen on March 22, 1977.
Apparently there was an extensive network of pieces connected with this across the plaza, but they failed to win public approval and were removed.
This piece stands almost forlornly but stubbornly alone.
Hajek was born in Czechoslovakia, but lived most of his life in Germany. The Adelaide work is not listed on his Wikipedia page.
I’m rather pleased with the symmetry in the photo. Full size here on Flickr.
