Internationally renowned sculptors have set to work at a site in the Adelaide Hills for the Sculpture Symposium in Hahndorf.

Each of the sculptors, from France, Turkey, Bulgaria, Australia, New Zealand, Georgia and Finland, has had a $30,000 work commissioned by a community of the Adelaide Hills and Fleurieu Peninsula region.

The sculptors will chip, grind and polish their lumps of stone over the next three weeks, with some young South Australian sculptors working as their interns.

The stone has been donated by a number of South Australian quarries, including red granite from Coober Pedy, marble from several areas and black granite from Black Hill.

Eight sculptures created at the 2012 symposium now are in permanent locations as part of a sculpture trail across the Hills and Fleurieu Peninsula.

After a further event in 2016, there will 24 sculptures in all forming the tourist trail.
