A friend drew my attention to a free online course, which apparently mentions Ravenglass at some point! The course is called: Hadrian's Wall: Life on the Roman Frontier - Explore the archaeology of the most heavily fortified frontier in the Roman Empire, its people and their lives.
The course started on 22nd September, so is now in its third week, but you can still sign up and catch up with everyone else. It is run by Newcastle University, and one James Gerrard, who came and scanned the Bath house at Ravenglass, also appears talking about pottery!
From a quick look at the first couple of weeks, besides looking at the Wall, it also considers the general background to the Roman army, and also the civilians who would have been around too. So it's not just about Hadrian's Wall, it also serves as a great introduction to the sort of Romans who may have also been at Ravenglass. It's well worth at look at can be found here.
