There’s a real-life treasure hunt underway and it’s just like the Da Vinci Code.
Five small gold objects, worth £1,000 each, have been hidden around Scunthorpe, North Lincolnshire.
And if you find them, they’re yours to keep.
But there’s one catch – you have to decode some hidden messages.
There are five paintings at the local arts centre.
All you have to do is find the secret codes encrypted within to unravel the mystery.
The mastermind behind this adventure is artist, Luke Jerram.
And the messages have been encoded by mathematician and professional code-setter, Dan Fretwell.
Eager code crackers queued up at the 20-21 Visual Arts Centre in Church Square this morning.
Jerram told the BBC: ‘There is no way I could crack the most difficult one, I could certainly crack probably two or three of the paintings.
‘Some are really easy to decode, whereas the most complicated painting, it would take maybe a month for someone to perhaps work it out.’
A few of the tougher codes are expected to take months to work out – if at all.
The five objects cast in gold represent items found in the North Lincolnshire Museum.
The Treasured City exhibition will run until April 29.
