There's a path near our house that circles another reservoir (theme?) and also goes through the ruins of one of John of Gaunt's castles. This old barn has nothing to do with the castle; in fact, it is across the reservoir from it. But, given that the "castle" is mostly rocks overgrown with grass, the barn ruins are more interesting.
Yeah... the British version of "old crappy building" sure is more charming than a rusted aluminum shed, isn't it?!?
