Archaeologists have returned to uncover a prehistoric ritual landscape that includes a Bronze Age cairn which may be larger than its famous neighbour Bryn Celli Ddu — a 5,000-year-old passage tomb aligned with the summer solstice sunrise on Anglesey.
The Welsh passage tomb might not be as recognisable as Stonehenge, but it has a similar alignment where the stones line up with the sun on the longest day of summer.
Excavation now suggests that the site had significance for prehistoric people that lasted for millennia after the earth mound was raised over a stone passage chamber.
The monument has an evocative Welsh name, which translates as ‘The Mound in the Dark Grove’ and was first excavated in 1865 and then completely reconstructed in the 1920s, but excavations over the last five summers – with members of the public joining archaeologists – have uncovered a 'rich' landscape of archaeological remains, covering more than 5,000 years of human activity.
Pupils from local primary school Llanddaniel Fab and several others from across Anglesey have been given special access to the site learning about life in their area 5,000 years ago.
