Streetmuseum: Londinium iPhone App Review
All the sites are overlaid on a modern map of London, so you can see how the city has developed over the years. You can even perform your own virtual archaeological digs using your fingers to dig in the earth, while blowing on your phone’s microphone will remote dirt. There are augmented reality features too, and walking guides that use your handset’s GPS abilities to keep you on track.
It’s a bit gimmicky in places, but Londinium offers up plenty of information and is largely a fun way to discover the Roman origins of many of the capital’s most famous streets and landmarks.
