SHOPPING vouchers worth £150 are up for grabs in a new social media contest.

The Bluestone Throne — a giant chair made to look like Stonehenge — will be in five different locations in Salisbury city centre over the next five weeks.

Entrants need to find the throne, strike a pose, take a snap, and post it on Instagram or Facebook using the hashtag #bluestonethrone

The most imaginative entry will win the vouchers.

BID marketing manager Stephanie Shearing said: "We wanted to bring an exciting and interactive element to the Salisbury for both residents and visitors and to add an element of surprise or fun while out shopping, grabbing a bite to eat or visiting the city for the first time and it appeals to everyone with a nod to our local history."
