We used to have Energy Conservation meetings where I worked and the brother of one of the delegates from Sheffield Hallam University was the " keeper of the keys" at Windsor Castle. I told him we were planning a family visit and he put me in touch with his brother. He showed us round the castle and we saw rooms normally not open to the public. My mother in law was in a wheelchair, so he let us use the Queen Mothers private lift. It's a right place and somehow " obscene" to think all that space is devoted to one person.
