Naturally as you would expect, this barrow had a tradition of fairies seen dancing and playing round it. According to J C Davies’s ‘Folklore of West and Mid Wales’ (1911) (noted in Bord’s ‘Fairy Sites’ of 2004), prior to it being included in a garden it stood in Fairy Field, and the oak tree itself stood on top of it. Bones and pottery were found when it was excavated in 1882. Perhaps you know whether fairies are still seen here – the Royal Mail certainly believes (scroll down the article at news.bbc.co.uk/1/hi/wales/2205201.stm).
Not far away is another barrow, perhaps also saved by the grace of gardeners, known as Hillbury. The idea of a fairy oak and a fairy mount is reminiscent of Irish fairy folklore?
