A wee while ago I did a bunch of research on the Old Wife/Cailleach. I found this tale on a website, which to my shame I cannot credit because I've lost the disc with it on. Anyway it's my favourite tale as it incorporates a number of the common elements of the Cailleach/Old Wife tales
"An account from 1894 tells how in Co. Meath, there is a set of chambered cairns on a hill which is known as Sliabh na Caillighe, meaning "the Hag's mountain," or "the witches' hills." It is located near Oldcastle and Lough Crew. The hag, whose name was unknown by the shepherd who told the story, had brought the stones in three apronfuls to the three primary cairns. She placed a stone to serve as her seat, or chair, on a hill point called Belrath. Now, the stone is called Chair Cairn. This stone is ten feet long , six feet high, and two feet thick and is hollowed out in the center. There are notable zig-zag designs and concentric circles engraved in the stone. Around the base and in front of the stone there is a fairly large quantity of quartz which has been broken into small lumps and strewn around. It is said that Cailleach placed the chair here did this so that she could look out upon the countryside whenever she wanted to. The hag loved to ride a pony she had that would leap from hilltop to hilltop. One day, the hag rode the pony so hard that it fell down, and both the horse and the rider were killed. The Cailleach in this story also gives her name to Bearhaven in Co. Cork."
