While not strictly folk-horror, the event had enough vaguely folk-horror elements for me to include it as the third of my folk horror blogs. Glastonbury, and of course the famaous Tor, is well-known as a place that attracts people for a variety of spiritual reasons (and also for a certain music festival, though that may be horror of a different type). The Tor rises above the town. From its summit you can see the vale of Avalon stretch away, flat and wide. Artefacts from the iron age have been found on its slopes; it has links to Arthurian myth. The sense of location, of dislocation common across folk-horror themes is there in abundance.
You can get a good idea of what went on from this youtube video by Megalithomania.co.uk (and you may even spot me on it at some point). Many many thanks to all who organised, took part and made it all happen. Happy Samhain/ Halloween to all.
