Beltane is an ancient Gaelic festival celebrated in parts of Ireland, Scotland and England with roots connected to May Day; however, you will see in the collection of pictures that Beltane is the darker side of the springtime holiday. Since 1988, Edinburgh has hosted the Beltane Fire Festival where 1,000s of participants and spectators come to watch the story of the May Queen as well as a staging of the Green Man’s death and rebirth.
