The British postal service was originally established in 1516 as a department of the Government but has changed drastically since then. Today, the company provides mail collection and delivery services throughout the UK, which are processed in one of its 1,400 delivery offices. But some have been lost with time.
In 2015, the ‘Hidden Spaces’ project was started to uncover some of Birmingham’s hidden architectural landmarks – including a huge sorting office beneath the surface of the modern upmarket Mailbox shopping centre.
Incredible photos and images showed that most of the original fabric of the Seventies letter and parcel sorting office that once stood still exists – including a tunnel that does not appear on any maps.
Up until the Sixties, the Royal Mail’s Birmingham postal centres were based in two buildings on Victoria Square, connected by a bridge.
But in 1970, a huge new sorting office was build, adjacent to the city’s canal and an underground connection was to be made to New Street station.
And so a 400-metre-long tunnel was constructed to allow small electric trucks known as BRUTEs (British Rail Universal Trolley Equipment) to pull cages full of letters and parcels straight off the trains to the sorting office.
It is said that the link was so secure that jewellers across the city would post their diamonds to themselves on a Friday evening, as it was cheaper than storing them in a vault over the weekend.
Although the tunnel does not appear on any maps, it still exists.
In 2018, 20 photographers were given rare access inside.
The Royal Mail sorting office was moved to Aston in 1998 and a year later ambitious developers bought the site which now houses shops, restaurants and bars.

Mail Road engineer Ray Middlesworth said the railway is a well-kept secret but believes people should learn more about its rich history.
He stated: “The most common misconception when you tell people what you do is they think you work on the London Underground.
“People don’t know that Royal Mail had its own underground railway and it takes a little while to get used to the idea of that.
“If you intend to take ownership of it, then it becomes your own personal system, even though it’s the Royal Mail’s you do take care of it.
“It’s got a lot of history and people’s lives wrapped up in it, so it’s nice to see something continue going on from its path.”
In its first year of operation (2017–2018), the trains performed 9,000 trips totalling 6,213 miles, with the railway and museum hosting over 198,000 visitors.
