London has endless amounts of historic landmarks, from Buckingham Palace, London Bridge, The Tower of London and many more. 

But along with its many landmarks, there are some hidden secrets that lie within some of the most iconic features of the capital. 

At Trafalgar Square, away from the tourists climbing on the lions and painters creating art on the concrete, there is a hidden landmark that is truly one of a kind. 

The UK's smallest police station sits within the walls of the Square, and even if you walked past endless amounts of times, you've probably missed it.

The UK's smallest police station in Trafalgar Square

Britain's smallest police station is hidden away in the southeast corner of Trafalgar Square in a spot that is often overlooked. 

The tiny box is said to have space to accommodate up to two prisoners at a time but its main use was to hold a single police officer according to History UK.

It was built in 1926 by the Met Police and the idea was for it to be a watch-out station.

Originally there was a police box outside of Trafalgar Square tube station, but it was taken down over public objections, asking for a more subtle police box instead, seeing the birth of the police box inside an ornamental light fitting. 

The light fitting had to be hollowed out with a small set of narrow windows installed and a direct phone line back to Scotland Yard for reinforcements. 

Plus, when the phone was picked up, the light on top of the box would start to flash, making nearby officers aware.

Now, the box is no longer home to police and is instead used as a broom cupboard for the cleaners of Westminster Council.
