Wednesday 4th March. This month David Ratledge gave a talk on is favourite subject, Roman Roads. As you probably know David used to work for Lancashire County Council and was responsible for the creation of the very useful Mario website. He last visited us in 2010 but a lot has happened in the Roman world since then. David brought us up to date with all the latest developments both nationally and locally, particularly in the use of Lidar in prospecting for new sites.
