Among the articles we included in the August issue of E&T about how technology's underpinned virtually all aspects of the London 2012 Olympics, there are a few that we hope will appeal to readers without even a passing interest in the biggest show in town.

We didn't manage to find anyone competing in the Olympics or Paralympics who combines their sport with a career in engineering (contact us if you know of someone who does), but assumed that at least a few of the people visiting London for the Games will have an interest in technology.

So we put together a map of a few engineering-related sights, several off the beaten track, that you might like to take in during your visit.

The space we're allowed on Google maps doesn't leave much room to write about every location. They've all got a fascinating tale though, some of them literary.



If you've got a young family in tow you're inevitably going to 'do' the Houses of Parliament, so why not arrive by tube at Westminster Underground station? Then you can casually drop into the conversation, "Of course, this is the station Harry and Arthur Weasley come through on their way to the Ministry of Magic in Harry Potter and the Order of the Phoenix. Look at how the stacked banks of escalators are supported by cross-bracing structures spanning the station box. The original 19th century station was completely rebuilt in the 1990s, you know."

Further afield is Southgate tube station, the Grade II* listed Art Deco building (northernmost station on the network to be situated in a tunnel, tube fans) that features in the 1999 film of Graham Greene's 'The End of the Affair', among others.

We'll be adding to the map periodically. If there's something within the M25 you think an engineer visiting London would be interested in drop me a line and I'll see if we can add it.

You can pay through the nose for a guided tour of London's Harry Potter-related locations. Engineers will probably prefer the 'open source' approach of the-magician.co.uk's DIY tour.
