I've been visiting Cwm Orthin for about thirty years now and I've seen the buildings falling steadily into disrepair as nature takes them back over.
The quarry had a poor safety record which led to it being known as "the Slaughter House" and this small chapel was built for it's workers. I guess it must have seen some tragic times.
I have old negatives I took showing it in much better repair but when the back wall fell in a few years ago, so did most of the roof and these last timbers just point up to the sky like bony fingers now.
The sheep skull and the dead, rotting pine seem to complete the somber mood for me somehow.
