Tranmere Deep Shelter, Wirral


During the 1940's the Home Office gave the County Borough of Birkenhead the green light to build the most expensive deep tunnel air raid shelter of its kind in the country

With space for 4560 bunked and 1600 seated occupants, the staggering system below Tranmere reveals the importance placed on local labourers by the government

Simply put, if Wirral was to play its part in the war effort, the manpower of Cammell Laird and the docks had to be protected from Nazi bombing

Currently held by the National Archive, Cabinet Office document 10131/4363 puts the estimated cost of the venture at £119,000

It was decided in the event of a nuclear attack, the Tranmere bunker was capable of being used by the public, but a second system under Bidston was not capable at short notice due to rotten supports

In the post-war rush to utilise resources, the system was stripped, but the signage and brickwork remain

I Never thought this place would see the light again, and is certainly a grail as far as the Wirral goes!

Overlay produced by nick from a plan kindly sent from canute originally prepared by Stevie Wonder :rolleyes:


We dropped in near to what would have been one of the main 'usable' entrances for the shelter

A couple of side rooms and passageways going off in different directions, along with a toilet block a short distance away


In one of those side rooms, amongst the burnt remains of a commer van (obviously myself and The Kwan old enough to remember those) :p:


Not sure why that would have been in there, but alas no swag as the mighty plasma cutter had beaten us to it


Round the corner, a curious archway leads to a larger passageway, which appears to be the main drag in/out of the shelter


As you can see the passageway was blasted, the paved walkway looking a bit sorry these days compared to the rest of the shelter


Once at the other end, we were now in the confines of the main shelter


The layout of the shelter is a grid formation, very similar to Bidston, although this place was much bigger

We had a leisurely stroll through the various passageways and rooms which have been largely un-touched

Only the elements and signs of slight vandalism can be found here and there



^ Note the galvanised cladding used as a false ceiling, both aesthetic and also to protect against any falls from the sandstone above

Here, sections have been removed to expose the sandstone beyond




Sadly, the place is an accident waiting to happen :eek:

This fresh fall is only a few days old and it's fair to say caused by disturbances from the recent activity


There are a number of emergency exits from within the shelter, here an old escape shaft under Olive Mount



No shelter is complete without a number of lavatories, there certainly are plenty of them as up to 6,000 people needed to pay a visit








There was also a canteen down here..


Canteen it is, although you will have to sing for your supper these days

dish of the day - Asbestos :eek:


We had a look at the central control area, hidden away beyond a non descript asbestos clad door behind a toilet block

Here the remains of the generator and ventilation gubbins, along with distro boards and other switch gear

(also note another escape shaft, once concealed behind the 'false' ceiling)



And finally the main emergency exit that once led to the top of the hillside which sparked all that interest back in 2008


Up top, a ventilation shaft which once led to a surface building at the end of an alleyway close to Thompson Street


And lastly the +20m shaft looking back down from below the concrete cap


Sealed in 2008 of course ;)


Thanks to The Kwan for the heads up, Marsden, also shouts to Terry and big up the lad who fetched his mum in :thumb

A nice clean Bidston. Did you ever get that D800 working ?
I ended up with a new one, but I don't have any usable full frame lenses aside from a 50mm prime so it rarely gets used :(

I will invest in some glass this year and put it to good use, just I don't fancy taking it down sewers so I might have to start derping about again
