The Cabmen's Shelters: Inside London's secret 'green sheds'
7 August 2013 Last updated at 00:13 BST
To the untrained eye, they are green sheds - an incongruous sight on the busy streets of urban London.
But these wooden structures have, in fact, been part of the street-scene in the capital since 1875 - a refuge for taxi drivers to eat, drink and take shelter from the weather.
These days, just 13 remain - and many now serve the general public at large. But cabbies remain their core customer base. Now, as in the 19th Century, they are looked after by the Cabmen's Shelter Fund - a charity.
A grant from the Heritage Lottery Fund will now ensure their place in history is recorded. The Creative Intelligence Agency, a non-profit design and arts organisation, is working with the London Transport Museum to document the shelters' past, gather oral histories from cabbies and commission art works.
