Although originating in megalithic times, the commonest kind of bullaun is a portable stone associated with an ancient church or monastery, in which there is a deep, hemispherical depression.
we have one of the bullaun on the farm (convoy)not to far from this stone circle in Raphoe Approached via a farm lane leading W from a by-road running due S from Raphoe, this fine early circle (perhaps contemporaneous with, or a little earlier than, Ballynoe, Down) of 60 surviving stones averaging 1.6 metres in height is the kerb of a much reduced cairn, and similar to kerbed boulder-circles at Carrowmore in Sligo. Also known as Beltany, it is prominently sited on a hilltop, and affords wide views. Well outside the ring to the SE is a tall outlier. From the high pillarstone at the WSW of the circle a cupmarked triangular slab at the ENE marks the point where the sun rises on May Day (Bealtaine or 'Beltany'). There are also standing-stones to the N and NW.
