The likeness of Black Beauty in Great Yarmouth has been put behind a fence after it was found to have suffered from subsidence.
The issue comes less than three months after the installation of the trail of sculptures in Great Yarmouth.
A Great Yarmouth Borough Council notice on fencing around the sculpture read: “We are sorry this play area is currently out of action, awaiting repair and maintenance.
“For your own safety, please keep out of the area. We apologise for the inconvenience caused.”
