The QE2 mile is High Street and Above Bar street. Together this street runs through the old and new town as it links the city park and waterfront. Walk it from beginning to end to see the main highlights of Southampton.
The city of Southampton has done a really good job creating an open-air exhibition out of Southampton. In the old town they give you lots of information through tiles like these for example. Knowing where you walk does enhance the experience and Southampton really knows how to do this!
