Jessica has returned with some nifty shots of Giant's Ring. I asked her to explain it, and this was her response.
It's a late Neolithic or early Bronze age henge monument. The stones in the center are the remnants of a "passage grave"...the entrance to the center, which was a ceremonial site. It's surrounded by the big earthworks about 3.5m high. There's been some archaeological evidence of cremation pits and 3 rings of timber posts (think Stonehenge & Woodhenge, but smaller). The "grave" in the center would have been originally covered with earth.
If you click on the photo, you should be able to view a larger image. Thanks to Ray for suggesting that, and Jess for re-sending them all in a larger format.
For those who might want to know exactly where this is, you can click here. The circle is clearly visible (or should be--I still don't trust links to open the same way for everyone).
