Tree Henge

These tree "houses" are popping up all over the forest. Are they a rough shelter for extreme campers? Or perhaps of religious significance - a sort of wood henge.

Not sure I would fancy sleeping in one for the night so the mystery of why they are there continues. A puzzle of Stonehenge magnitude. 

It was beautiful in the forest today. I thought that the coffee stop venues might be crowded so I took a flask of coffee. I enjoyed a drink sitting on a log amidst this splendour. A good decision.

Thanks to Cailleach for hosting the wild Wednesday challenge.
