ARTEFACTS uncovered in Maryborough's Queens Park have been identified but how they got there remains a mystery.
Council has been working with archaeologists and museums to establish a display of hundreds of historic bottles after the cache was discovered during storm water drainage works in January.
"The first step was to identify everything which we've now done so the next stage is to do more research with historical societies and online to find what they were doing there," said Councillor for Community, Heritage and Family Services George Seymour.
"That part might not ever be solved."
Cr Seymour said work was stopped immediately when the bottles were discovered.
"After it was reported on the front page of the Chronicle back in January, the State government found out and immediately ordered a stop to the multi-million dollar infrastructure work as these were historical finds on a heritage listed site."
"These artefacts are fascinating and help tell the story of Maryborough's history."
The items include bottles for storing food such as vinegar, sauce and chutneys as well as cosmetic jars, inkwells and medicine and alcohol bottles, even a gramophone needle head was found.
