There are sculptural elements in the cityscape that appeal to the eye, there are those that challenge and inspire, and there are those that educate. But usually not as directly and powerfully as these pieces of twisted steel at Monash University. Although sculptural in appearance, they are remnants of a disaster - the failure of the West Gate Bridge during construction in 1970 that killed 35 workers. The fragments were taken to the university to be assessed as a part of investigations into the collapse, and were later put on display as an educative tool and as a reminder about the importance of getting engineering right!
There is also an evocative memorial sculptural work on the site of the collapse in Spotswood, which you can read about here.
