LOCKE Park Tower could open to the public this year after essential works costing £80,000 have been carried out to make it safe.
The tower had to be shut in the early 1990s because of structural problems but the Friends of Locke Park group is now working with Barnsley Council to try and get it open by the end of the year.
David Allen, one of the group's members, said: "The idea is to make it safe first so we can get the public in, and let them see what they're missing."
David said a survey has been carried out to assess structural defects and check its stability.
The conservation architect on the project is discussing the tower's works with English Heritage, as it's a Grade II listed building.
The tower was built in 1877 as a memorial to Joseph Locke's wife, Phoebe.
