A grass verge where people regularly park will be restored and improved to highlight a historic wall structure.
Stamford Civic Society and Urban Group are working with Lincolnshire County Council to repair the verge next to the Bastion, on the corner of West Street and Petergate.
The first step was to remove two trees, one of which was dying, and that was done in April.
The organisations now hope to level the verge with new soil, reseed it and plant spring bulbs. Two new, smaller trees will also be planted.
And wooden bollards similar to those on the verge in Wharf Road will be installed to stop people parking there.
The Civic Society and Urban Group hope the work will highlight the Bastion, which is the only one of 11 remaining from the town’s thirteenth century wall.
Civic Society member Peter Stevens said: “We want to level the site, sloping down in front of the rather nice stone wall and to the Bastion.
“People do park there and we are trying to stop that.”
Reader George Jeeves, 50, of Perth Road, contacted the Mercury after getting a ticket for parking on the verge.
He said it was unclear whether or not you could park there, and suggested installing wooden bollards to make it clear.
Mr Jeeves, a chef, said: “People are going to carry on parking there. You can see it’s been parked on for years.”
Lincolnshire County Council confirmed it was illegal to park on the verge as the road technically extended to the wall.
