I hope that some time it gets restored - although run-down places have their own appeal too. We used to visit a garden that was state-owned but not really maintained - it was a wonderful wilderness. It's still a nice place to visit now that it's better maintaine, but it's lost a lot of its character. And I'd love to visit a house in England where I once worked as a cook. The year after I left the owner made some agreement with English Heritage, but instead of restoring it totally I believe they run it as a way of showing what happened to old houses when the old money ran out and things ran down from their early splendour.
The creosote may not look interesting, but I was so glad you shared that photo. I assume it's what the creosote that used to be used for treating wood comes from, and I was fascinated reading about it. I love that smell!
