A 5-metre high wooden peg has been placed at the entrance to the park owned by South Kesteven District Council. Carved from larch, it is designed to replicate a peg holding a piece of clothing.
The new addition is the idea of SKDC Cabinet member for Planning Policy, Cllr Nick Robins, who wanted an added attraction installed that was out of the ordinary.
Cllr Robins was joined by the sculptor, Nigel Saderson, as he unveiled the peg on Sunday.
"I'm sure it will become a talking point for people in the park," said Cllr Robins. "SKDC iscommitted to making Queen Elizabeth Park visually attractive and welcoming for our residents and visitors, and this is a fascinating gateway piece for our open space area."
The park is undergoing an upgrade with the installation of a carpark, picnic benches, new seats, fishing platforms and bins, plus pathway repairs. The peg, meanwhile, could be the starting point for a sculpture trail through the park.
The peg is Nigel's second piece of public art in Grantham, having also created the Newton's apple sculpture in the sensory garden of nearby Wyndham Park.
