I really wasn't expecting to go to a ring cairn in Ireland, but I did and it is a great one.

How do I explain this superb structure? Right. Imagine a very large banjo. Place this on the ground. Build a 3m high cairn around it so that when you remove the banjo you have a circular clearing in the middle and an entrance passage where the handle was. OK so far? Now, build a stone circle around the inside edge of the clearing and insert several kists into the cairn around the outside.

There you go. Five points for the first person to build one!

The cairn, in the most part, is now higher than 1m now, but one section of it, opposite the entrance, remains to a height of three meters. The stones that make up the stone circle are no more than a meter tall and all pretty consistant.

It was a very pleasant surprise to be taken to this one and I can't wait for an excuse to go back or the chance to see another one.
