Thanks for the feedback! Honestly I think that Claude did not take Westminister on the map because it thought that it was only a parliament, not an actual palace. You are right here.
For Whitehall, I will do further verification because the fame listing comes from how famous the place is on Wikipedia. If there are no historical value and the fame comes from it being a city district, then I would have to delete it.
I will see to it later today.
