Behind the present kirk is Tom nan Angeae, the hill of fire, where until the 19th-century hearth fires were renewed at Beltane and Samhain to encourage ancient gods to bring warmth to the land. St Angus was buried at the foot of this hill and a flagstone laid over him which stands today in the present church. This stone, formerly in the floor of the medieval church, has a crudely incised figure of a priest holding a chalice. The carving is probably late medieval in date.
