Welsh burial mound has 5,000 years of history

Archaeologists have uncovered a prehistoric ritual landscape in Anglesey which they believe may include a cairn cemetery.

Excavation work at Bryn Celli Ddu, a 5,000-year-old burial mound, suggests the area was an important site for prehistoric people, and its useful significance may have continued for millennia.

The structure was first excavated in 1865 and heavily reconstructed in the 1920s, but summer digs over the past three years have uncovered 5,000 years of activity on the mound, including 10 examples of rock art carvings and worked flint tools.
