The site, recorded on the old Ordnance Survey six-inch maps under the name Billew Burial Ground, is what is known in Ireland as a cillín, an informal burial place used for unbaptised infants and others excluded from the rites of the Church. These sites are scattered across the Irish landscape in their hundreds, often at field margins or on older, half-remembered sacred ground, and Billew is among the more obscure of them. No enclosing wall or ditch marks it out from its surroundings, and what remains visible are simply set stones indicating graves oriented east to west, the traditional Christian alignment placing the dead facing the rising sun.
