Time for a summary: A building in London, north of the river, built between 1700 and 1800, part of which is still standing. It is (or was) partly open to the public, overground, and on a street. It is not: a religious place, a bridge, the Houses of Parliament, a prison, a fortification, St Pancras Station, Marble Arch, the British Museum or Highgate Cemetery. Nor does it have any health connection. The question “Do you have to pay to go in” produced laughter from the audience and the response “Quite the reverse”.

add "Not a residence" to summary.

[I] (applause!) Yes! These very words appear on the card! But that is not the whole answer.
[R] I don't know if any of the Bank of England's officials ever had their residence there.
[I] Not exactly.
