West Kennet Longbarrow

From the photographer: “This photograph is of the West Kennet Longbarrow with the constellation Cygnus above. The barrow is over 6,000 years old and was completed before nearby Silbury hill and Avebury stone circle were started. It is earlier than the first phase of Stonehenge.
Archaeoastronomer the late John North believed the interior chambers
lined up with Cygnus.” © Pete Glastonbury
