Dozens of druids took to the top of Primrose Hill yesterday afternoon as they continued an almost 300-year tradition in marking the first day of autumn.

Clad in long white robes, the annual event to mark the equinox saw them trek up the Hill while chanting hymns.

The first public meeting of Druids on Primrose Hill was in 1717, ending hundreds of years of having to meet in secret.

A plaque atop the hill commemorates the Welsh Druid priest who first called the meeting – and William Blake, who was part of the Druid order, has had his poetic words inscribed in stone on the hill.

The ceremony is one of three events staged by the Druid Order, with the spring equinox ceremony at Tower Hill and the summer solstice held at Stonehenge.
