'The Spheres' (affectionately titled the 'Mall's Balls' by locals) is Rundle Mall's most iconic artwork.
Made from a pair of larger-than-life stainless steel spheres sitting one atop the other, the artwork measures just over 4 metres tall and was brought to life by Vienna-born artist Bert Flugelman.
Flugelman always wanted the artwork to be interacted with:
The Hindmarsh Building Society donated 'The Spheres' to the City of Adelaide in 1977 to mark their centenary.
Today, 'The Spheres' is a popular meeting place, with most Adelaide locals having met someone at the Mall's Balls when visiting Rundle Mall.
Their shape has become synonymous with Rundle Mall and Adelaide as a whole, appearing on posters, t-shirts — and even the Rundle Mall logo.
You'll often see kids playing with the artwork's reflections and tourists taking a photo of themselves using 'The Spheres' as a backdrop.
