Archaeoastronomy update Ancient monument aligned to sun

An archaeologist has discovered that the passage into a burial mound on Anglesey was built to catch the rising sun on the summer solstice.
Steve Burrow said he was "elated" when the sun filtered in through trees as he sat in the Bryn Celli Ddu chamber.

He made the discovery as he researched a book about burial tombs in Wales from 4,000-3,000 BC.
