WORK is under way to discover more Bronze Age secrets on Bodmin Moor.

Archaeologists taking part in the Mapping The Sun project have revealed sections of a stone causeway at the Hurlers standing stones, near Minions.

The path is thought to be part of a processional route used 4,000 years ago between the Hurlers and Rillaton Barrow. It is believed to be the only one of its kind in the UK.

The research at the Hurlers will continue into the weekend with the aim of putting a date on the creation of the path, said Iain Rowe, of the Caradon Hill Area Heritage Project.

'We can lift some of the stones and we're hoping to find dateable evidence underneath. The archaeologists will take samples of things like pollen, in order to accurately date when the stones were laid down on the ancient land surface,' said Iain.

A team from Cornwall Council's historic environment department has been carrying out the excavation, with lead archaeologist Jacky Nowakowski guiding volunteers.

'It's quite rare to get permission to be able to dig on a scheduled ancient monument. Everyone's really excited and people have come from far and wide to join in. The number of members of the public that have visited has been amazing,' Iain said.

The stones used for the causeway were first excavated in the 1930s.
