London Police stations

This is supposed to be the world's smallest police station. I don't know if that is true but it is only big enough for one policeman. It is on the corner of Trafalgar Square in London and was put there so that police could keep an eye on demonstrations in the Square during the 1930s depression. It had a direct phone link to Scotland Yard Police station which was then just a few hundred metres away.
It is no longer in use as a police station but is said to contain cleaning equipment.

This is another small police station which is on Bird Cage walk next to St James's Park. This station is still in use by the Royal Parks Constabulary. You can just see above the station the traditional blue lamp.
