[2] Newspaper editor George Armstrong and The Earl of Shaftesbury took it upon themselves to set up a charity to construct and run shelters at major cab stands.
[3][4] The idea allegedly came to Armstrong when all the cabbies seeking a pub's refuge and warmth on a snowy night in St John's Wood rendered him unable to hire a taxi there.
[5] These shelters were small green huts, which were not allowed to be larger than a horse and cart, as they stood on the public highway.
Between 1875 and 1914, 61 of these buildings were built around London, the first being on Acacia Road in St John's Wood near Armstrong's home.
They are located at: During annual Open House London Heritage Days, the public gets a chance to see inside some of the shelters, normally the exclusive reserve of cab drivers.
