Burial chambers dating back to the third millennium BC will be the setting for a series of events to celebrate the Summer Solstice as part of a project led by Cadw and the Arts Council of Wales.
 
The project ‘Horizons: Old and New’ will centre around Barclodiad-y-Gawres, one of the most significant Neolithic passage tombs in the British Isles and the impressive chambered tomb, Bryn Celli Ddu. The project will culminate on the weekend of the Summer Solstice (Saturday, June 21 and Sunday, June 22) with a series of events including a dawn celebration at Bryn Celli Ddu, hosted by the Anglesey Druid Order (around 4.30am on June 21).
