Marden is mid way between Avebury and Stonehenge.
8 miles from both and they are all in a rough alignment.
The Henge is the largest in the country.
The Hatfield barrow used to be inside the henge but the antiquarian, Cunnington, totaly destroyed it.
I have just got back from there and posted a new pano with glowing dandelions etc.
(See link in my post above)
Very few people know much about it at all, this prompted me to research the place for 3rd Stone with Neil and Brian.
