A secret doorway

This morning I went out with the walking group and had a lovely walk around the Pradoe area. We passed this door set into a wall on the edge of a big house and barn complex. Apparently it is a door into their walled garden - I'd have loved a peep inside!
I don't think that the door can be used these days as there was a greengage tree blocking the access. The tree was laden with fruit and I'm afraid that most of us scrumped a greengage as we passed by. There was so much fruit and they were so sweet that it's a wonder that the owner hasn't picked them by now. I know that I would have done!
