Reclaimed by nature

These are the derelict iron furnaces on the hill opposite us.  They were cleared a little a couple of years ago but nature soon reclaims them.  It must be a hundred years since they were last used.
Today has been a quiet day, church followed by the removal and treating of the next shutter.  That's five down and seven to go.  They won't all get done this visit and I am a bit late getting round to them anyway as one is already a bit rotten. It's not a job I have to do in the UK!
