You might think an archaeological feature as big and apparently well scrutinised as Hadrian's Wall would have little more to give up in the way of secrets. Peter Benn of the Hadrian's Wall Tourism Partnership finds this idea amusing: "In fact, there are all sorts of things going on - artefacts are constantly being dug up and new sites discovered all the time."A great way to keep up with new developments at this World Heritage Site is to visit the Tourism Partnership's website. Within this easy-to-look-at site are embedded links to news pages about the latest digs, details of new finds and information about where you can see relics in many local museums.So just what is being discovered? "In parts of Newcastle, there are areas where the wall has still not been traced, and the effort goes on to remedy this," said Peter Benn. "Recently archaeologists found a new section quite near the inner city Byker area."There are links for the more academically minded, guidance notes for walkers and also educational resources available. It's the sort of detail rich site that repays persistant visits.
