Deep Tunnels

I passed by an interesting structure one day. Well, actually, I pass by it everyday.  It is round and brick, and there is a sign on it that says "Deep Tunnel Storage To Let".  I wasn't sure what that meant, but it sounded curious. I snapped a picture and then didn't think about it again for a few days.

A few days later, I got to thinking about it, so I googled it.  It was pretty interesting, I thought. There were several of these Deep Tunnels built around London for use as air raid shelters during World War II.

Wikipedia says:
Each shelter consists of a pair of parallel tunnels 16 feet 6 inches (5.03 m) in diameter and 1,200 feet (370 m) long. Each tunnel is subdivided into two decks, and each shelter was designed to hold up to 8,000 people. It was planned that after the war the shelters would be used as part of new express tube lines paralleling parts of the existingNorthern and Central Lines. Existing tube lines typically had 11 feet 8.25 inches (3.56 m) diameter running tunnels and about 21 feet (6.4 m) at stations; thus the shelter tunnels would not have been suitable as platform tunnels and were constructed at stations the new lines would have bypassed. However, they would have been suitable as running tunnels for main-line size trains. 

Ten shelters were planned, but only eight were completed: at Chancery Lane station on the Central Line and Belsize ParkCamden TownGoodge StreetStockwellClapham NorthClapham Common, and Clapham South on the Northern Line. The other two were to be at St. Paul's station on the Central Line and Oval station on the Northern. The working shaft for the shelter at Oval now functions as a ventilation shaft for the station.[1]
The shelters were started in 1940 and completed in 1942. They were originally all used by the government, but as bombing intensified five of them were opened to the public in 1944: Stockwell, Clapham North, Camden Town, Belsize Park and Clapham South. The Goodge Street shelter was used by General Eisenhower, and the Chancery Lane shelter was used as a communications centre.

Post-war use

In 1948 the Clapham South shelter housed immigrants from the West Indies. The MV Empire Windrush arrived in Tilbury in 1948 carrying 492 immigrants. London had a severe labour shortage after the war and the Colonial Office had sought to recruit a labour force from Jamaica. An advertisement had appeared in Jamaica's Daily Gleaner on 13 April 1948 offering transport to the UK. The Windrush was quickly filled. As there was no accommodation for the new arrivals, the Colonial Office housed them in the deep-level shelter at Clapham South.

After the war, the Goodge Street shelter continued to be used by the army until the 1950s, and the Chancery Lane shelter was converted into Kingsway telephone exchange, as well as being expanded to serve as a Cold War government shelter.

In popular culture

The Goodge Street shelter appeared in studio mock-up form in the 1968 BBC Doctor Who story The Web of Fear, while the real location appeared as itself in the 1988 feature film Hidden City, written and directed by Stephen Poliakoff.

The Camden Town shelter was used to represent parts of Oval tube station in the 1976 two-part story The Lights of London in the BBC television series Survivors. The director of the second episode was Pennant Roberts, who subsequently directed the 1977 Doctor Who story The Sun Makers, in which the same shelter was used for scenes set in tunnels under Pluto. Roberts subsequently worked on the BBC series Blake's 7, in which the shelter was used to for the interior of the titular artificial planet in the 1980 story Ultraworld, although the episode itself was directed by Vere Lorrimer. The shelter was also used to represent parts of a secret underground facility in the vicinity of Down Street tube station in the 2005 feature film Creep.

The photo that you see above is the Stockwell location, I believe.  The same day that I googled the deep level tunnels, I noticed this one on the corner of Clapham Common, near the Clapham South tube station (the nearest one to the Upper School), on the corner of Nightingale Lane (where the Upper School is located).  

I really found this interesting. If you think it is interesting too and want to read more about them, and see some great historical photographs of the interiors of deep level tunnels - this is a good website to visit -
