I particularly liked the Castle of Mey, the late Queen Mother's Scottish residence, which is very homely as are the gardens.
My Fairy Queen, when not gardening herself, loves walking in her Palace grounds and finds this a major source of relaxation. As far as her realm is concerned, a relaxed monarch is one who is not going to be panicked into making irreversible and life threatening (to others) decisions or to take her world into unnecessary wars.
When part of your garden looks like the image below, you know you have something rather special!
