A forgotten house?

Overgrown letterbox and doorbell

There’s an old locked gateway on the Eisenbrand with its own bell and letterbox. The drive looks dark, overgrown with bushes and ivy. The house is not even visible from the road. You could easily walk past a dozen times without noticing it. If you were writing a ghost story set in Büderich, it would make a wonderful haunted house setting. Time to sharpen my pen again?
