Cromwell Road

 was a London street in SW7. Along with Exhibition Road, it formed a corner on which the Natural History Museum was found. It was also likely a street on or near where one of the entrances to the Knightsbridge tube station was located. When confronted with a sudden afforestation outside the museum, Danny Pink ordered his charges from Coal Hill School to begin finding their way back home by following the street lamps on Cromwell Road.
