Hi, its a long shot but a friend has put a post on facebook of her daughter visiting a place with her dad (who has now passed away), she wants to revisit but has no idea where it was, she can remember it took a little while to get there from Bristol and this was within the last few years.
picture one is of a large wooden pagoda type structure with decking and grass growing on the roof.
Picture two is of the base of a tree with a little door made from bark with a sign saying fairy door.
Webbo.....lots of woods have fairy doors......Wayford in Somerset for example. Could she google....fairy doors in UK woods and see if anywhere rings a bell......x
If you can't solve your problem here, a local newspaper might print the photos and ask their readers for their help. (Our local rag does things like that).
