Building and Burning the Wicker Man
24-30 October, St Fagans National History Museum, Cardiff
Many moons ago, the ancient Druids set large wicker statues on fire as sacrifices. Nowadays, the wicker man is less entangled in religion and belief, instead becoming a centrepiece at festivals and outdoor autumn events. St Fagans build a wicker man every year in the week leading up to Halloween, before setting it alight on the Halloween weekend. It's free to help to build the wicker man and to watch it burn – see their website for timings. Why not go on a Morbid Curiosities tour around the darkest corners of the museum while you are there?
