Slates used to write on in a school more than 100 years ago have been discovered under an old staircase by a community group renovating the building.
Now members of the Oban Communities Trust plan to preserve and display the slates in an exhibition at the Rockfield Centre in the town.
The former Rockfield School was saved by the community after it was nearly bulldozed to make way for flats.
The building has been empty since 2007, but now the trust is working to refurbish it and turn it into a centre for community groups, art culture and heritage.
Eleanor MacKinnon, project worker for the Rockfield Centre, said: “The slates have been found under an old staircase that has been closed in for quite a number of years. They are damaged with woodworm. We have taken advice and we think we are going to be able to save some of them.
“We are going to put them in casing so that they can be handled.
The others that have already lost the wooden cover will be used in our oral history display in November during Oban Winter Festival.
“There will be recordings of former pupils taking about their time at Rockfield and artefacts will be on display.”
Some of the slates have still got chalk marks on them but are not legible. One gives the number of boys and the number of girls in the school in 1902.
One of the wooden covers has initials on it and the trust members are trying to trace the individual’s name through the archives.
Ms MacKinnon added: “Over the summer there has been a massive amount of voluntary work done. We had a massive clear out.
“Most of the flat roof at the back of the school has been repaired. All dry rot areas have been exposed and had the initial treatment. We are now letting the air circulate the building.
“Our next stage is clearing three or four classrooms for a theatre production we are hosting in November.”
