The Druids might well have considered it sacrilege to have had as much fun as this.
Sacrilege is the name of the inflatable artwork that brings the ancient British monument Stonehenge to life as an irreverent full-scale bouncy castle in the centre of Perth.
The free family-friendly collision of history and contemporary art is the creation of Turner Prize-winning artist Jeremy Deller.
There were plenty of volunteers keen to test it out when it opened in Supreme Court Gardens yesterday.
Sacrilege was made as part of the cultural festival for the London Olympic Games in 2012 and has since toured the world.
But the Perth heat would give it its toughest work-out, project manager James Hutchinson said.
"We hose it down between each session, so it does cool down," he said. Despite its size, Sacrilege will take just three minutes to pump up each day until the end of the Festival on March 1.
