On Sunday 5 December there is an opportunity to participate in a special historical experiment.
The hillfort glow experiment takes place in December
North east Wales' Heather and Hillforts Project and Cheshire West and Chester's Habitats and Hillforts Project will attempt to communicate by torchlight between 10 ancient hillforts.
The experiment, funded by the Heritage Lottery Fund, willl involve local people close to 10 hillforts on the Sandstone Ridge, the Clwydian Range, Halkyn Mountain and the Wirral and aims to see if glowing fires could have been seen across the hills and acted as a communication or warning system.
Iron Age settlements can be found on many of the summits of the Sandstone Ridge, Clwydian Range and surrounding hills, dating back around 2,500 years.
Flares will be launched from the hillforts followed by torch light at Maiden Castle, Beeston Castle, Kelsborrow, Helsby, Burton Point, Moel y Gaer Rhosesmor, Penycloddiau, Moel Arthur, Moel Fenlli and Caer Drewyn.
Volunteers can help with this mass experiment by helping to man each of the 10 hilltop signaling points. Places are strictly limited, so to register to help as a volunteer for your local hillfort, visit.habitatsandhillforts.co.uk.
Once registered, volunteers will be sent information packs with exact timings to meet and what to bring.
Further details about the Hillfort Glow experiment can be found on the North east Wales' Heather and Hillforts Project website.
