Bryn Celli Ddu: Summer Solstice 2020
Unfortunately, due to Covid-19 pandemic, it has become necessary for Cadw to announce that we will not be able to host the summer solstice celebrations at Bryn Celli Ddu this year.
Please do not travel to Bryn Celli Ddu on the 20 or the 21 of June, as the site will be closed.
Due to concerns over the further spread of Coronavirus and the well-being of our visitors, we regret to report that all Cadw unstaffed again enjoy these outstanding monu monuments and car parks will be closed from 5pm Monday 23 March until further notice. We do look forward to inviting people to oncements as soon as we are able.
Iconic Neolithic tomb with a celestial secret
One of Anglesey’s most famous prehistoric landmarks, Bryn Celli Ddu (the ‘Mound in the Dark Grove’ in English) is actually two sites in one. In the early Neolithic (New Stone Age) period, a henge (bank and ditch) enclosing a circle of stones was built here, to be replaced later by a chambered tomb beneath a mound measuring up to 85ft/26m in diameter. Inside, a long, narrow passage leads to an octagonal chamber 8ft/2.4m across, where artefacts such as human bones, arrowheads and carved stones have been found.
But Bryn Celli Ddu’s most unusual feature can only be seen once a year. As the sun rises on the summer solstice (the longest day of the year) shafts of light shine directly down the tomb’s passageway to illuminate the chamber within.
