As it says, The Victorian Fernery, Benmore Botanic Garden, Dunoon, Cowal, Argyll & Bute, Scotland.
Not sure why, but I didn't take any shots inside apart from on my phone but it's a fascinating building. Benmore, as I said in my last post is well worth a visit and if you don't like gardens don't be put off by the word in the title. We didn't visit much of the formal garden this time at all and managed to spend 4 hours or more there. Great place to walk the dog.
