The example at Rougham fits that description precisely: the boulder measures roughly 1.75 metres north to south and 1.6 metres east to west, and is lifted between 15 and 20 centimetres above the ground by five support-stones, with two additional pad-stones filling the gaps. What makes it quietly unusual is not the archaeology alone but the memory that has gathered around it.

Local tradition holds that the field containing the boulder was known as páirc an aonaigh, which translates roughly as the fair field, a place where a large fair was held in ancient times. More specifically, the boulder itself is remembered as the surface on which payments were made and deals sealed. That detail is worth pausing over. A monument that may be several thousand years old, originally erected as a burial marker or territorial sign, appears to have slipped into a secondary life as a kind of transaction stone, a fixed and weighty object lending formality and permanence to the agreements struck around it. The boulder sits in rough pasture on the level ground south of the Kerry River, with traces of older field boundaries visible about 50 metres to the west, suggesting this corner of bog has been divided, worked, and remembered for a considerable stretch of time.
