Boxes of artefacts belonging to a museum, including many which have never been displayed before, are being unpacked by members of the public.
A total of 6,658 boxes from the Museum of Gloucester's collection are being sorted at the city's Discovery Centre in Eastgate Shopping Centre.
Lizzie Johansson-Hartley, the museum's collection officer, said Anglo Saxon leather and a Roman tile with a print of a dog were among the "amazing" items which had so far been unpacked, relabelled and "preserved for the future".
Archaeologist Mark Horton said the year-long project made archaeology "accessible" to the public.
Ms Johansson-Hartley said some of the boxes had not been opened up "for 50 or 60 years".
"We're making sure everything is preserved for the future.
"We wanted to be in a public space particularly because we wanted to open up the heritage that we have hidden away in storage to the public," she said.
