Heading south, alight from the Docklands Light Railway at Island Gardens, just after the entertainingly named 'Mudchute' stop. Follow your GPS to N51° 29.185 / W000° 00.567 where, overlooking the Thames, you'll find a baffle to stop people walking along the top of the embankment past a wall. The first question used to be how many spikes are there on this baffle? While you're here, take a look over the river to see your (former) second target. The answer you now need is below your feet...
Take a walk. This will be MUCH easier between 6am and 11pm. If you don't fancy the stairs (and there's quite a few of them) take the lift (if it's working! - Actually, the new ones are reliable). The good news is this route is both free and wheelchair friendly. At the bottom you'll find a narrow section of tunnel, made from X rings of painted metal plates. Please MESSAGE me how many rings!
IGNORE THIS OLD QUESTION. It's here for historic reasons only! At N51° 28.994 / W000° 00.630, in the shadow of a much bigger sister, you would once of found a famous mobile home. Question Two used to be what was the first name of the person who designed its Self Steering Gear and was then what are the three digits on the fire hydrant plate on the curved wall, right of the doorway? However, since the structure has been behind wood for months and will be for months more, there is now only the one question to answer; how many rings of plates make X?

While you're in the area I suggest you try Carharty's Greenwich Hemispheric Exploration or else Whisky Galore by kimrobin. Both are within very short walking distance.
September 2007 update: The tunnel and both its ends appear in the film '28 Weeks Later', I see. October 2011: The tunnel was also site of one of the world's first underground marathons, back in 2002, to mark its centenary. A similar race was hoped to be held in Woolwich tunnel in 2012 to mark its 100th year too. But wasn't.
