Drombeg AKA The Druid's Altar Drombeg is probably Irelands most famous stone circle, it is a recumbent circle with the recumbent or altar stone lying to the south-west. The circle consists of seventeen pillar stones that are graded from the two large portal stones, each 2 metres high, at the north-east towards the recumbent stone. The pillar stones are local sandstone and the recumbent has two cup marks and what looks like an axe -carving on it's upper surface. Towards the centre of the image left are two stones, male left, phallic shaped and the female right lozenge shaped..
