An excavation is underway at Wales' largest hill fort, which dates back thousands of years.
It's hoped that local volunteers will get involved and discover their own history as part of the CAER Heritage Project in the Caerau area of Cardiff.
Mike Griffiths reports
The team have always believed the fort was occupied by an Iron Age tribe before the arrival of the Romans.
It's now thought the site could be even older, with some parts dating back to the Stone Age.
Getting more local young people involved is one of the project's main aims.
University students are working on the dig alongside local schoolchildren
The organisers hope many more people will get to visit the site before the dig ends later this month.
