A disappearing wall has been rediscovered at an Edwardian manor house in west Devon.
The owners of Coombe Trenchard Manor discovered the moving wall after a villager said she had read that the house had the feature.
The current owner, Sarah Marsh, said: "We live in a house full of panels, it could have been anywhere."
It took Mrs Marsh three years to discover the wall.
