There is a tiny building in the heart of Birkenhead that many people will walk by every day and not really notice it.
Some can be forgiven for thinking it is just an old relic left behind from the 1800s when the town was at the epicentre of Wirral's industrial boom.
And they wouldn't be wrong.

But while it sits next to the historic Woodside Ferry terminal at the top of Shore Road and between the old gates along the former tram lines, the one-storey structure once had a unique purpose.
Built in the mid-1800s, it has been dated from 1868 and was used as a police booth close to the ferry.
The sandstone structure was given Grade II listed status with Historic England in 1999 alongside the gates on either side - also made of the same sandstone ashlar, a type of material synonymous with 'grandeur'.
Historic England said: "It is a single-storeyed, single-cell structure, with polygonal ends and rear entrance.
"Single-light windows are divided by attached shafts to outer elevation.
"The booth was built to control principal road and pedestrian access to the dock, as part of the work undertaken by G.F. Lyster, the engineer."

Today, the booth remains locked with no clear indication if it will ever be opened again as weeds grow from the roof and the windows all boarded up.
Due to its listed status, any repair work would have to use traditional methods and remain in keeping with its historic features.
It is not the only tiny building that was once used as a hub for the police.
284A Poulton Road in Wallasey,Wirral, is easy to overlook as you make your way to Central Park or drive past on the bus.
The pint-sized structure on the corner of the park has proven to be a very versatile unit over the years, having once been a police sub-station and a sweet shop.
In the mid-1970s it became a taxi rank -perhaps the perfect size for a person to coordinate radio hire cabs.
But that changed by the end of that decade when it became a tobacco and sweet shop.
That closed by the 1990s, but this was not the end of the ingenious uses for the brick building.
The current owner applied for permission from Wirral Council in 2000 for it to become a recording studio.
And that is what it has been ever since, offering specialised sessions for vocalists in the sound-proof booth.
