A popular question asked at Hercule Poirot Central is: where in London is Whitehaven Mansions, Hercule Poirot's home as seen on the television series "Poirot"?
Such a question deserves a feature, c'est vrai.
It is found on Charterhouse Square in London. Many buildings surround the square, but "Whitehaven Mansions" is located on the eastern side of the park. It is just north of the Museum of London (at London Wall). The Museum of London's postcode is EC2Y 5HN, whereas it is known that Charterhouse Square's postcode is EC1.
For visitors not familiar to London, Charterhouse Square is just west of Goswell Road/Aldersgate Street and one block north of Beech Street. One can always go to Holborn Circus, and from there take Charterhouse Street in a northeast direction up to the Square.
Another thing: if you're near the Barbican Centre, home of the London Symphony Orchestra and the Royal Shakespeare Company, you know you're close. The Barbican Centre is adjacent to the Museum of London.
