As part of our commitment to offerring new and innovative ways to explore London, we're currently trialling a new quiz walk around London that can be completed on your mobile phone as you walk around the historic streets of the old City.
The St Paul's and Smithfield Quiz Walk is a free DIY Walk that you do on your mobile phone and which takes you around the fasciating area that srrounds St Paul's Cathedral.
You'll see some really interesting, and hidden, parts of London, and there are plenty of places - pubs, cafes, parks and churchyards - where you can sit and rest as you make your way around.
You'll even get a certificate at the end of the walk that will detail your score!
It's best to allow 3 hours to really enjoy the Quiz Walk.
