Bryn Celli Ddu Burial Chamber

Isle of Anglesey (Ynys Môn)

There are neolithic burial mounds scattered all around Wales, but many have been completely stripped of their earthen covering by over-enthusiastic archaeologists and left as a stone shell. What makes Bryn Celli Ddu fascinating is that it's relatively intact; you can enter the barrow and pass into a stone-lined burial chamber that was used as a communal grave 5000 years ago.

To find it, follow the signpost off the A4080 down the country lane to the marked car park.
