As part of the Preston Guild 2012 celebrations (only held every 20 years), they had the installation (it's art, honest!) Sacrilege installed onto Frenchwood Park in the city. It is a full sized replica of Stonehenge. Turned into a bouncy castle. We had to get there very early to ensure a 'go' on it

Their website is here with more explanations, and hopefully it will tour again next year so the rest of you can have a go! An Inflatable Stonehenge on Tour by Jeremy Deller, bouncy castle
