Members of the Shakti Sings choir sing as druids, pagans and revellers gather in the centre of Stonehenge, hoping to see the sun rise, as they take part in a winter solstice ceremony at the ancient neolithic monument of Stonehenge near Amesbury on December 21, 2016 in Wiltshire, England. Despite a forecast for cloud and rain, a large crowd gathered at the famous historic stone circle, a UNESCO listed ancient monument, to celebrate the sunrise closest to the Winter Solstice, the shortest day of the year. The event is claimed to be more important in the pagan calendar than the summer solstice, because it marks the “re-birth” of the Sun for the New Year. (Photo by Matt Cardy/Getty Images)
